The biggest thing I see as a possible - and I mean possible negative, is the effect on recruiting. Of course, you've recruited well since Tress has been there, so that looks a little suspicious at first blush. I do not follow recruiting as closely as many here do. And it seems like every fan base always moans and groans the stud recruits that got away. Gators do too. But I sometimes see folks bemoaning losing some close battles on skill players, and if this is not just the ordinary fan grumbling at not getting every one, then maybe the difference in losing some of those offensive guys is a perception of a style of play that is less attractive to kids who want to be on ESPN hi-lites every game, and who view their shot at being seen as - um- "electric" superstars would not be served by the Tressel offense.
I do not know this, this is not my assumption, and I have NO facts to back this up. I am merely thinking out loud on this, because honestly, I cannot see that much to complain about. (Jax is right that discussion about the issue is valid, and complacency will get you second place every time) Really, winning a major conference championship year after year after year, etc., etc., should pretty much diminish much of that criticism.
