Conference Tournament Predictions 2015 – Final Results

Three years ago, I compiled predictions for the conference tournaments from three sources–my own, Ken Pomeroy, and Team Rankings. When the dust settled, Team Rankings had narrowly edged out KenPom for the title as I lagged behind a distant third.

I didn’t get around to it in 2014 (though perhaps I can find time to go back and gather predictions from that season), but last year I did track things. Unfortunately, I’m just now getting around to posting it. The results were the same, though this time, Team Rankings won comfortably over KenPom and my own predictions. I’ve posted the full spreadsheet on Google docs, which you can find here. I discuss the scoring system in this post. Since we are posting advancement odds, we don’t have predictions for each individual matchup. Instead, predictions are essentially a rolled up version of all possible matchups. To score them, I use the log of each team’s predictions to get exactly to the round they did. For instance, my predictions for Montana in the Big Sky tournament were 81%/61%/43%, meaning an 81% chance of winning the 1st round and advancing to the semifinals, 61% of reaching the final, and 43% of winning the title. Another way of looking at it is that Montana had a 19% chance to lose in the 1st round (that’s 100% minus the 81% chance to win in the 1st round), a 20% chance of winning one game and then losing in the semis, an 18% chance of winning twice and losing in the final, and, of course, the 43% chance to win it all. Those are the probabilities that are scored.

This year is under way. If I get around to it, I may post the predictions for each of the three systems, but either way, I’ll be back in a couple weeks with the final results. Good luck to Ken Pomeroy and Team Rankings; I hope to be able to at least climb out of the cellar this year.
