ESPN just ran a list during the WV-Pitt game:
Offensive Formations of the Top 10 teams-
Florida, Texas, TCU, Boise St, Oregon
And my favorite-
if only you could be good and run spread football...
(And while the competition may not be the best, it's not exactly tropical in Boise)
Edit: I just noticed in their usual wisdom ESPN had 9 top 10 teams. The other would be Cinncy, also a spread team.
