Inside The 2010 NCAA Bracket: Predictions (And Stats)
Ken Pomeroy is your friend. You may not know it yet, but he is. Pomeroy, of the eponymous kenpom.com, has been the pioneer and leading evangelist of tempo-free statistics in college basketball. For the uninitiated, tempo-free statistics show how efficient a team is: how many points they score and allow per possession.
The basic idea is that any counting stat -- points scored/allowed or rebounding margin, for instance -- gets distorted by a team's pace. Fast-breaking teams have more opportunities to score and get rebounds (and conversely allow more points), but that doesn't necessarily mean they are any better on offense (or worse on defense) than a plodding, half-court team. Pomeroy's efficiency ratings allow for an apples-to-apples comparison between stylistically different teams (hence the "tempo-free").
When it comes to filling out your bracket, Pomeroy's ratings are useful not for telling you who to pick, but rather who not to pick. It turns out that the "defenses wins championships" mantra is mostly right when it comes to college hoops. Teams that don't rate in the top-25 of defensive efficiency rarely make the Elite Eight, let alone the Final Four. As for the teams that typically advance to the national semifinals, they are, unsurprisingly, generally in the top-25 in both offensive and defensive efficiency; in other words, they're all-around elite teams. By simply eliminating the teams that don't meet these criteria, you can get a much simpler look at which top seeds have realistic aspirations to make it to Indianapolis and which don't.
We've broken down each region, listing the teams that have a chance to win the region ("Contenders"), those that have a good shot at making the Sweet 16 ("Best of the Rest"), and the lower seeds that could crash the party ("Cinderellas"). Teams' offensive efficiencies are listed first, followed by their defensive efficiencies.
