2012 NCAA Basketball Preseason Top 25: Did The AP Whiff On Michigan?
posted in NCAA Basketball
After a long weekend poring over spreadsheets full of stats, ratings, recruiting data, and transfer lists, we’re ready to publish our official college basketball preseason projections.
This article is the first of several college basketball posts we’ll make this week. Today we’ll start with our preseason top 25. Later we’ll publish the full list of 347 teams, along with information on why each team is ranked where they are. We’ll follow that with conference projections.
Finally, we’ll be revealing a cool new feature that we created over the summer, which we’re really excited about. But that’s staying a secret for now!
Just a quick reminder to start: the ratings below are completely data-driven, with no manual fudges. The main inputs to the system are past team ratings, rosters and player stats from the past few seasons (which allow us to calculate returning offensive and defensive value, as we did last year), and recruiting info. So if your favorite team is over or underrated, rest assured it’s not because we hold some grudge against them. We’re just reporting what the historical data is telling us.
Without further ado, here is our preseason top 25. Below the table we’ll discuss a few of the teams for which our projections differ significantly from conventional wisdom, as well as reviewing how our preseason ratings performed last season.

Three Overrated College Basketball Teams
Before we get into discussing over- and underrated teams, let’s explore one quick question: Should you even care which teams we think are overrated?
The (limited) data suggests you should.
Last year six teams ranked in the preseason AP Top 25 did not make the TeamRankings preseason top 25. Of those six teams, only one even received a single vote in the final AP poll from last season, and three finished 49th or worse in our end-of-season predictive power ratings:
|Team||AP preseason||TR preseason||TR final||AP final|
One more key team not listed here is UConn. The AP poll had the Huskies 4th in the country prior to the start of the season, while he had them 11th. They finished 40th in our predictive ratings, and didn’t receive a single vote in the final AP poll. On balance, if a team was ranked in the AP preseason Top 25 but not in our Top 25, it was bad news for that team.
So what teams are we raising red flags about this year?
Michigan (AP #5, TR #39) — This an enormous difference, bigger than anything we saw last season. A quick check of other data-based projections reveals that most are more down on Michigan than the AP is: Pomeroy has Michigan 12th, and Dan Hanner has them 44th. So we’re not totally going out on a limb here.
Why are the Wolverines so low? The answer seems pretty simple, really. They were 31st in last year’s ratings, which form the baseline for this system, and they have only an average amount of returning minutes compared to the teams that were rated ahead of them. They have a couple borderline impact recruits, but nobody that’s a game changer, and have no incoming transfer help unlike several teams ahead of them. As a result, we are projecting them to be roughly as good as last year.
We wouldn’t be surprised if Michigan is better than the 39th best team in the country. However, it would be a pretty big bucking of past trends if they are really the 5th best.
North Carolina State (AP #6, TR #25) — We’re guessing the issue here is that NC State’s solid finish to last season (their only two losses in their last 8 games were by 3 points to UNC and 2 points to Kansas) is biasing people. Humans are prone to such “recency bias” as we stat geeks like to call it. Our ratings, however, weigh the 18-11 start to the season almost as heavily, so the Wolfpack are starting with a much lower baseline.
They do return quite a lot of value-weighted minutes, but simply returning a lot of minutes on a good-but-not-great team doesn’t make them great. (See Vanderbilt, last season.) On top of that, none of their major contributors last year were freshmen, whom are generally the players who make the biggest year-to-year improvements. So we see a mild improvement in NC State’s rating, but not the huge jump the AP voters are predicting.
Louisville (AP #2, TR #14) — Louisville ranked only #178 in raw offensive efficiency last season, which is very bad for a team aiming for elite status. This season, they lose Chris Smith and Kyle Kuric, two of their most efficient players. That means a heavier load will be placed on the shoulders of a few players that were very inefficient last year, particularly Peyton Siva and Russ Smith.
Unless those players show massive improvements, we just don’t see how the Cardinals’ offense can possibly be good enough for them to rate #2 in the country.
Three Underrated Colege Basketball Teams
Our preseason ratings didn’t do quite as well at identifying underrated teams as we did overrated teams last season, but we still picked out a few sleepers. Half the teams that were in our preseason top 25 but not in the AP’s ended up as borderline top 25 teams at the end of the year:
|Team||AP preseason||TR preseason||TR final||AP final|
We also picked out Missouri’s improvement before AP voters did. The Tigers were 10th in our preseason poll but only 25th in the AP Top 25. At the end of the year, the Tigers were 7th in our predictive ratings and 3rd in the polls.
Here are three teams we think may be similarly poised to beat expectations in the 2012-13 season:
Marquette (AP #26, TR #9) — Out of all teams that went unranked in the preseason AP poll, Marquette is ranked the highest in our preseason ratings. It’s easy to see why the AP voters see the Golden Eagles declining. Losing Jae Crowder and Darius Johnson-Odom leaves them with a big gap to fill on offense. Our projections see transfer Trent Lockett and rising sophomore Davante Garnder helping to ease the transition. We also project Marquette will maintain a high defensive level; they are above average in our returning defensive value metric, and Lockett had good defensive stats for Arizona State last season.
UCLA (AP #13, TR #5) — It’s important to note that our UCLA rating assumes top recruit Shabazz Muhammad will be cleared to play this season. If he’s not, the Bruins will drop down to a borderline top 25 team. That seems like a huge drop for one player, but Muhammad is rated as the top recruit by some scouting services. Imagine if Kentucky last year was missing Anthony Davis.
We’re wondering if voters aren’t feeling a little buyers’ remorse from last season. They made UCLA #17 only to see them stink up the joint. The Bruins definitely were a disappointment last season, but they have a Kentucky-esque recruiting class this year. That injection of young talent should be enough to push them to the top of the Pac-12.
Wisconsin (AP #23, TR #10) — Losing Jordan Taylor is a huge blow to Wisconsin’s offense, and frankly, we’re a bit worried that our projection may not adequately account for that. However, the Badgers were actually ranked much higher in defensive efficiency (8th) than they were in offensive efficiency (42nd) last season, and their defense shouldn’t take as big of a hit in Taylor’s absence as their offense will.
Besides the fact their defense could be elite once again, it’s always dangerous to count out a Bo Ryan club — he’s nabbed a protected NCAA seed five of the past six seasons.
So, there you have it, our preseason top 25. What do you think? What other teams do you want to talk about? Are we completely whiffing on any teams? Leave any questions or comments in the discussion thread below.
