Why are there so many upsets in college football in 2007?

It is call parity. Recruits don't automatically go their respective state schools anymore. They go where they think they can play right away and win. The college recruiting process has gotten better as well. Schools look all over and not just locally. The overall talent of the athletes is getting better. When you recruit a player, you never know what he/she may turn out to be a few years later. Being away from home and playing with the top amateur athletes takes some players longer to adjust - if ever. Some players cannot accept not being the best anymore. Some rise to the occasion. The bottom line, sometimes you get lucky with your recruits and their development and sometimes you have wait till next year.
