College football preseason rankings are ridiculous considering the teams haven't played a down, and these four teams are overrated compared with what they can accomplish this season.
Only once in the BCS era has a team started No. 1 in the rankings and finished with a championship trophy in hand (Florida State in 1999).
Even worse, since current reigning champion Alabama did so in 1978, it's only happened two other times (Florida State in 1993, Oklahoma in 1985).
Point being, perception can be deceiving from the top all the way down.
Considering what key players these four squads are losing, they are overrated going into the 2012 season.
