I still think Harbaugh can lean back on his NFL experience to show recruits he can get guys to the league, even if he hasn't actually done it at Michigan.
Michigan have sent a bunch of good defensive players to the league in the last few years (Bush, Winovich, Uche, Gary, Peppers, Charlton) and a handful of ok to good linemen (Ruiz, Cole, Glasgow), but the best skill players they've had drafted are DPJ and Jake Butt. Either the recruitment is derriere or the development is - either way good talent is going to think twice about going to that program right now.
