I have found him impressive thus far. Granted we haven't seen his recruits on the field yet so time will tell, but I'm not expecting a bunch of four stars to walk through the door now that we have him as our DC.
1. He's able to make adjustments, albeit a little slow for us, but we move in light speed.
2. He didn't have enough depth last year, but this year he will (for rotation).
3. Now in his 2nd year preparing a defense that has an offense like ours.
4. He's been a HC, experience counts.
If our defense tanks year two I would change my mind.
