College football Top 25 Projection

This summer has been busy.  I have managed however to find some time to tweak the formulas I've used to predict team strength and come up with some composite rankings.  The changes centered a lot on removing some emphasis on turnover luck (it really has a very low significance for explaining year to year variability), and redid my returning experience formula.  It should help give a much better view of a team over a season, since the formula had a new reduced standard error equal to about half of what it had been.

In season I'll be making a few tweaks to what happens for a team afflicted with injuries, which of course will as the old military adage goes, ruin this ranking at first contact.

Team Ranking
Alabama 1
Ohio State 2
Southern California 3
UCLA 4
Oregon 5
Oklahoma 6
Baylor 7
Stanford 8
Florida State 9
Notre Dame 10
Georgia 11
Texas A&M 12
Texas Christian 13
Mississippi 14
Arizona State 15
Clemson 16
Oklahoma State 17
Michigan 18
Texas 19
Missouri 20
Texas Tech 21
Michigan State 22
Florida 23
Arizona 24
Miami(FL) 25

It loves the Pac-12, which I think will continue to shine.  I do doubt though we see USC, UCLA and Oregon in the top 5 or so at the end of the year.  I'm also not nearly as high on Florida, but they could be a darkhorse with that defensive secondary.

The program also generates odds for a team to win a range of games, which I'll sort by below, going from the best chances to win at least 11 games in the regular season.
