Agreed. Conner is better running north and south with a FB leading the way. Folks (including Fichtner unfortunately) seem to forget that his best running two years ago came with Nix leading the way.
Take into account Snell is more a North and South runner as well. I'm not sure what they did mainly at UK, but the guy would also seem to benefit running out of a traditional I formation. Ebron is pretty terrible so far w/ his inline blocking and Vance never much wowed me either, so go a little old school coach.
Ben worked defenses off of the play-action from I's in his early days.
