I like the hire, and like it even more after watching some of the videos out there of him working with other college and high school coaches. I recommend anyone who hasn't watched the video to take a look.
He appears to be a good teacher. The focus of his system is on making it easy for players to understand their responsibilities. The defense is still aggressive. What more could you ask for? Especially with 3 new starters in the defensive backfield next year.
If the offensive productivity doesn't drop off significantly, a jump in pass defense like the one Arkansas made last year ( 113th to 72nd ) would likely be enough to win the B1G.
