SPEED ON DEFENSE!! That's why option football, with the exception of the military institutions, is dead! Did you see what happened when Crouch and the '01 team went up against Miami in the NC game? Let's face it, speed kills and team defensive speed is too much these days at too many schools. Plus I don't think you'll have a guy as fast as Crouch come around for quite some time.
The same thing was said in the 80's/early 90's then low-and-behold, along came Frazier, Berringer, Frost, Crouch...3 NC's, mulitple conf championships, Unitas Award, Heisman Award....etc.
Has the game evolved, sure, it always does. Read Frosts blog, he would know, he has played the game. He even said that the players are not THAT much faster and THAT much bigger now. To prove that, look at NU's D, this years D is not anywhere as close to the speed that the Ds had in the 90s. Switzer said the same thing at the NU-OU game.
Almost any offense would work, given then right players and coaches. The option has proven that is can win games consistently in college football.
