Well, I think they made a big mistake with the 2008 class. They completely overestimated their abilities and rough ridin' whiffed on everything. Got CK, though, which was nice. But I think this was a real slap in the face for them.
They've definitely shifted their strategy to offering lower level recruits earlier. It really isn't a bad plan as long as you don't think replacing Fred Brown with Martavious Irving and Ron Anderson with JHR is a good idea - these second tier recruits often end up being pretty good players as juniors and seniors.
aTm is a good model of this. Under Turgeon, they really don't have a lot of roster upheaval, so they've been led by a a solid core of 4-5 juniors and seniors every year. None of the recruits have been real head-turners, but they've been able to get decent minutes as freshmen and sophomores which prepared them to lead the team as juniors and seniors.
