Why Polls are Not an Effective Way to Choose the top 2 FBS teams


Given the current regular season scheduling method, it’s impossible for pollsters to compare top FBS football teams with the precision needed to select the best two (or four).  Why?  There are 124 schools with teams competing in the FBS during the 2012 season.  Those teams are divided up into 11 conferences, along with a few teams that are independent.  Nearly all the teams play just 11 or 12 games against other FBS teams, and the vast majority of those games (8 or more) are played against teams within their own conference.  Therefore, while the system is set up nicely to judge the best teams within a conference, there is very little head-to-head evidence established to compare the top teams in each conference to each other.  The math is fairly straightforward.  Teams in each conference play just 2 or 3 FBS games outside of their conference.  Since there are about 110 non-conference schools available for each team, it is likely that only one of the non-conference games will be against a top-35 (or better) team.  It’s inevitable that any system designed to select just 2 teams out of 124, or even 4 teams out of 11 conferences, is going to appear unfair to fans or coaches most of the time, if there are few head-to-head battles as a basis for comparison.

Compare this to NCAA Division I men’s basketball.  There are currently 345 teams, also organized into conferences (32 this year).  A typical NCAA basketball team plays approximately 30 regular season games, with about half of them against non-conference foes.  In fact, many top teams schedule at least a half-dozen non-conference games against other top-50 teams.  With such a large number of non-conference games available as evidence, and a post-season tournament that includes 68 teams, it is not difficult at all for a national consensus polling system to precisely select all of the top 25 teams for the tournament.  In other words, even if two experts disagree on nearly every pick for the top 25, it’s virtually certain that all of their picks will have a chance to earn the national championship on the court.  I am not saying the NCAA Division I basketball tournament selection process is flawless, nor am I saying that the FBS needs to have a 32- or 64-team playoff - I am merely pointing out that the expert polling system is a viable option for identifying top basketball teams, but not a good system for football because of the significant differences in how the regular seasons are set up.
