Ohio State recruits very well obviously, and Ohio has good HS football. I agree with your point of course. Texas recruits get pulled in a lot of directions, but UT has to be a major player there for most. California has good HS football, as does Florida, with large populations, but again, a lot of programs from which to choose. Florida should be consistently very good to elite, but as we've all seen in spades, coaching ...
Mark Richt was, I think, a "pretty good coach", better than terrible, maybe even a notch above average, but not elite. I've only seen two elite coaches of late in CFB, Saban and Meyer. Meyer in particular won nearly everywhere. Kelly is starting to impress me also, we'll see. The "winning everywhere" is a key metric for me. Smart obviously has done great things and is still learning, and works hard, but he hasn't "won everywhere", not had the chance (unless you count as DC).
Saban didn't do much at MSU. We'll see about Reilly at USC and Day at Ohio State down the road I think.
