Honestly, I think our collective enmity for Grantham in most ways is rooted in his connection to the Humpers. It still sickens me. Aside from that, my biggest complaint is his apparent weakness on the recruiting trail. But let's face it, he's far from the only one on this staff that leaves a lot to be desired in that category. On the plus side, I can see how playing in that defense would be a lot of fun.
I agree with the consensus - he's not the best - but I think we could do a lot worse.
On a somewhat related note, the Clowns have hired Jim Leavitt as a defensive consultant. Honestly, I think this is a great move for them. Aside from choking that kid out, he did a truly remarkable job building USF from the ground up. I seem to recall his defenses being stout wherever he went.
