Craig is an elite recruiter, but is not a WR coach. QB coach maybe though EJ Manuel has not progressed much.
Ellis Johnson is an old out of touch DC that runs a permanent nickel defense.
Harbison is average at best.
Garner has done less with more than any DL coach in America.
Melvin Smith is a very overrated DB coach. Just look at how MSU has been torched for the last few seasons. Just another recruiter. I am sure you will all just dismiss this as anti-Auburn, but time will show I am correct.
