1/9 A10 Postseason Odds Report
January 9, 2009 by Mike Scullin

A little bit of a change in the way I calculate the odds starting with this edition. Instead of assuming a team has a 75% chance of receiving an NCAA bid if they reach exactly their target record, I now have it broken down by 3 confidence levels: 60%, 75%, and 90%. I think this will provide a little more accuracy; for instance, Richmond and URI are clearly better bets to make it at 11-5 than Dayton is at 10-6, and the odds now reflect that. I'm leaving the NIT confidence level alone at 75% for all teams since that tournament's selection process is a bit more objective and straightforward.

TR = target record for NCAA or NIT at large bid
TRPI = target RPI rank for NCAA or NIT at large bid
[C] = confidence level of at-large bid at target finish
NCAA%/NIT%/PstSn% = percent chance of reaching the NCAA tournament, NIT tournament, and one or the other, respectively, as an at large bid.

Why are Xavier's odds so high? A couple of reasons. For one, the schedule strength analysis in my last article convinced me that if Xavier finishes 12-4, they will probably amass a nice handful of high quality wins in the conference along the way. I bumped their target record down by a win to account for this fact (previously their target was 12-4 with an extra win over Florida), and their stock rose accordingly. Second, the Sagarin predictor and Kenpom formulas may love Xavier (and arguably Temple) a little too much right now. They both have Xavier projected for 13 conference wins right now in addition to a 50/50 shot for another big win @ Florida -- certainly doable for a very talented team, but 12 A10 wins would be a much more realistic projection. Remember that the game predictions are based on this data, so as a result the odds model loves Xavier to get to 20 wins.

Huge jump for conference All of the at large contenders have either been taking care of business or losing close games to good teams on the road, and as a result all of their NCAA chances have risen from the last report. The A10 adds 0.41 expected NCAA at large bids, and the chance of 5 bids skyrockets this week to 14%. Of course, that final number should be taken with a grain of salt -- it assumes the teams' quests are independent events, which they are not.
