Louisville scored more points than Oregon, and thus the official rules of college basketball declared the Cardinals the winners. However, a thorough analysis by yours truly suggests that the Ducks shat their collective pants during the first ten minutes of play, and that is why the Cardinals were eventually declared the winners.

Oregon did everything it needed to do to win the game…in the last thirty minutes. It out-rebounded Louisville, turned the ball over less often, and even shot a blistering 49% from the floor. I say “blistering” because the Cardinals had allowed opponents just a 39% clip before their matchup with the Fighting (why?) Ducks.

It was a good season and a valiant effort for the over-achieving Ducks. I guess it’s just hard to play over your head for a full 40 minutes.


Livin’ on more than a Prayer

March 28, 2013

Oregon-LouisvilleWhen you look at the top-scoring teams in the country, it seems like you have to scroll down forever to get to Louisville; the Cardinals are tied at 41st in the country with Santa Clara in points per game at 73.6.  You have to go even further down—all the way to 107th—to find the Cardinals in field goal percentage at 44.5%. That’s just below Oregon’s 44.7%, and additionally, Louisville was 219th in three-point percentage on the regular season. How, then, can Ken Pomeroy rank Louisville’s offense 10th in Division I basketball?

There are a few good answers to that question. Though Louisville shoots a low percentage from the floor, there are other components to offensive efficiency. The Cardinals, for instance, are 9th nationally in offensive rebounding percentage at 38%. That means that Louisville rebounds nearly two of every five of its own misses! It’s almost okay for them to shoot poorly.

Rebounding. Check. But the Cardinals are actually not so good with ball security, ranking 101st in turnover percentage. Turnover percentage is a more relevant stat that TO per game because it controls for a team’s pace of play. Faster teams will naturally turn the ball over more times per game because they’ll get more chances to cough it up. Louisville is but average in this category.

So far, it’s hard to figure out how Pomeroy has them rated so highly. With an average turnover rate and below average shooting, even a great offensive rebounding percentage doesn’t seem like enough to rank them so highly. Enter strength of schedule. By looking at all the season stats from teams that Louisville has played, we can assess how good those defenses were. It turns out that Louisville played a bunch of teams that tended to stymie the opponents’ offenses. Louisville’s schedule featured the 12th best group of defenses in college basketball.

Now we start to see why that Cardinals offense might be more potent that it looks on the surface. In its two Tournament games thus far, when given the chance to play against inferior competition, Louisville shot 56.9% from the floor, and 43.5% from three. If they’re open, the Cardinals can put it in the peach basket.

But having arguably the 10th best offense overall doesn’t add up to a top seed all by itself. Louisville has one of the best defenses in the country, and here’s why. Good defense starts and ends by reducing the opponent’s efficiency, and Louisville does that well. Opponents shoot just 39% from the floor against the Cardinals, leading to those opponents scoring less than one point per scoring attempt (factoring in free throws, the most efficient shot in the game). Among the 16 teams left in the tourney—quite the selection of talented teams—Louisville is fifth in opponents’ points per scoring attempt. Not a fantastic shot blocking team, the Cardinals must be really good at forcing tougher shots. Oregon is not a great shooting team—though recently they have tried to convince us otherwise—and things could get ugly if the Ducks’ shot selection is not top notch.

Oh, and one more thing. Louisville forces turnovers at a ridiculously high 27.4% rate, good for second in the country.  More than a quarter of opponents’ possessions conclude with handing the ball right back to the Cardinals for free. This is another area where a Louisville strength lines up with an Oregon weakness. The Ducks turn the ball over like it’s a hot potato. Their 21.2% turnover rate ranks them 265th in the country, and like with shooting, things could get ugly if Oregon is as careless as it has been the last two Tournament games.

So how do the Ducks win a game like this? Well, it would definitely help if Dotson went 5-6 from deep again, but counting on lights-out shooting performances from a team that has shot 126th in the country overall is a bit optimistic. Oregon can win by doing other things, so long as it doesn’t shoot itself out of the game or give the ball away for free.

If Oregon wins, I’d bet this guy is your player of the game.

Louisville has some weaknesses. Despite an excellent offensive rebounding rate, Louisville is ranked 175th in defensive rebounding. My old coach, who also happened to be my dad, once posed the following logic to me. A guy that grabs as many offensive boards as defensive boards could be a guy that just works his ass off on both ends, or he might not know how to box out leaving himself with equal chances of a rebound on either end. Louisville could very well be an athletic rebounding team, but not a technical rebounding team. Oregon, on the other hand, is ranked in the top 30 in both offensive and defensive rebounding. If Oregon really is more technically sound on the glass, then the Cardinals’ offensive rebounding advantage could be turned around on them.

Additionally, I mentioned that Louisville’s typical opponent was a better-than-average defensive team overall. Well, it turns out Oregon is also a better-than-average defensive team. Pomeroy estimated that Louisville’s opponents gave up 96 points per 100 possessions on average. Oregon gives up just 87 points per 100 possessions according to Pomeroy’s formula, which adjusts for competition. That’s 9th in the country! Louisville should not such an easy time scoring as it did against North Carolina A&T or Colorado State, and when they miss, the Cardinals should not have such an easy a time getting a second chance.

Here is how Louisville did against Pomeroy’s top 30 defenses.

This is definitely an impressive chart for Louisville. A +5.1 point differential against what amounts to all Tournament teams is nothing to scoff at. But among these matchups, Louisville did struggle with the likes of Villanova, losing in their first matchup of the season, and it struggled in a three-point victory over Pitt. Oh, and it lost four games. Impressive doesn’t mean perfect.

One last thing to look at, as I promised I would in my article yesterday, is luck, or better put, “Luck.” Pomeroy’s luck statistic basically compares a team’s win-loss record to its average point differential. Teams that outperform their average point differential in the win column are said to be “lucky.” I don’t think Pomeroy actually believes all of the discrepancy is due to luck, and nor should we. There are things teams can do to win close games, where the point differential is only a few points. Oregon performed well in close games this season, as evidenced by its +6.3% luck rating. Louisville, on the other hand, performed a little below average at -3.3%. Oregon definitely got some favorable outcomes, as the Washington game in the Pac-12 tourney comes to mind, but it probably does something to help itself in the clutch, too, and I think it has something to do with execution.

In five of the last six seasons, Dana Altman’s teams have finished better than their point differentials would suggest, implying an ability to win close games that goes beyond lucky timing. It could very well be that the man at the helm for the Ducks has his players thinking situationally, and has them just as prepared to execute in the clutch as any other time in the game.

It will be an uphill battle to beat the top-seeded team in the country, but Oregon has the defensive firepower to give the Cardinals fits and keep the game close. And the Ducks just might have an advantage in a close game.


What is a Billiken?

March 23, 2013

Wikipedia did some scouting on the Ducks’ opponent today, the St. Louis University Billikens:

The Billiken was a charm doll created by an American art teacher and illustrator, Florence Pretz of St. Louis, Missouri, who is said to have seen the mysterious figure in a dream. In 1908, she obtained a design patent on the ornamental design of the Billiken, who was elf-like with pointed ears, a mischievous smile and a tuft of hair on his pointed head. His arms were short and he was generally sitting with his legs stretched out in front of him. To buy a Billiken was said to give the purchaser luck, but to have one given would be better luck.

So, perhaps St. Louis has luck on its side, but didn’t get a lot else out of that scouting report. I read further:

Today, the Billiken is the official mascot of Saint Louis University and St. Louis University High School, both Jesuit institutions, and both located in St. Louis. The Billiken is also the official mascot of the Royal Order of Jesters, an invitation only Shriner group, affiliated with Freemasonry.

It turns out that “[t]he denomination with the longest history of objection to Freemasonry is the Roman Catholic Church,” and now I’m just confused. So, while Wikiepedia was quite helpful, I’m not about to put all my eggs into one scouting report. The seeding suggests that St. Louis is the better team, and Wikipedia suggests it might have more luck, but the Tournament has seen quite a few upsets, and Oregon has already directed and produced one of them. Let’s take a look at how Oregon might pull off a trip to the Sweet Sixteen.

Oregon is not a great scoring team. As usual, I’m not talking about totals, but rather, efficiency. The Ducks’ 44.5% field goal percentage ranks 104th in D-I hoops, and despite a recent barrage of long-range marksmanship, their 32.4% from three-point range doesn’t often save them (227th nationally…ouch!). Defense and rebounding—mostly rebounding—have gotten the Ducks to where they are today. Oregon’s best chances probably lie in the fact that one-game playoffs are a hotbed for statistical variance. Some kid can make eight triples in one game, and then go 2-for-12 the next (his name was Tajuan Porter). But two things that teams have a lot of control over from game-to-game are ball security and rebounding, and the Ducks happen to be good at one of those. Admire some statistics:

Margin Pace TS% OReb% DReb% TO%
Oregon 8.2 68.3 53.6% 34.9% 70.9% 21.6%
St. Louis 10.9 63.7 55.5% 28.1% 70.7% 17.8%

Both teams have solid margins of victory, an all-around summary of a team’s success on the scoreboard, but Oregon carries a heavy offensive rebounding advantage. Because I calculated rebounding as a percentage of missed shots here, Oregon didn’t get some sort of hidden advantage for being a bad shooting team. They did, however, recruit the likes of Arsalan Kazemi and Tony Woods, two guys that grab a lot of rebounds. The Ducks earned two additional field goal attempts and four more free throw attempts per game than its opponents, thanks mostly to their offensive rebounding.

While Oregon gives itself more chances on the glass, it takes away chances from itself by turning the ball over more frequently than do the Billikens. With point guard Dominic Artis looking good and healthy, Oregon has a better chance to shave the turnover deficit while maintaining a rebounding advantage, and that could very well be the key to an upset.

Any one game can be decided by a hot shooter or a few bad calls, but if the Ducks are able to nab a high percentage of the available rebounds, and outperform their turnover rates from the regular season, then they’ll significantly improve those chances of an upset.
