I have no idea if Clark Lea is head coach material, success at DC means nothing And, ND has been down that road, see Bob Davie Id much prefer a candidate with proven success at the head coach level..BK could be still at ND 5 years or more, his current contract has 4 years left at a minimum THat's way too long for a "coach in waiting" even if I agreed to that principle..
Just pay Lea top dollar for a DC And if he does leave, for HC, You'll have a much better idea if he's the one to succeed BK...
