Hmm top ten team that runs a variation of the WCO...No one ever hear of USC? It is a pro style offense, and really, at this day and age, pro style and WCO are about the same thing. Of the teams in he top 10, only Florida and West Virgina(who wont be top ten come the next round of polls) run a pure spread. OU, Texas, LSU, Cal, OSU, and Wisc alter what they run based on the QB, and right now, they are all running more of a pro-style set than the read-option.
Right now, if the defense was playing like it did in the 90s, no one would be talking about the offense.
