While taking a look at what other predictions others have about college hoops, I came across Dan Hanner’s blog and his comments on the accuracy of preseason rankings - at least for the outlets who rank all 351 teams. Hanner took a little time and compared the preseason rankings before 2016-17 to the final rankings from Jeff Sagarin’s rankings.
And before you go looking and howl at some team over some other team, know that Sagarin’s rankings, like Ken Pomeroy’s rankings, are based on assigning a performance-based rating to each team and how it would perform against an “average” Division I team.
