My opinion on him has nothing to do with the fact that he was a high-school/aau coach. It's the fact that he is Georgia Tech Hall of Famer who knows what is required to be successful here. He played professionally for 10 years, and I'm sure he knows X's & O's.
It doesn't matter if kids remember him from he played or not, but it's not like he's an old fogy. All this said, I agree that he needs some more seasoning, but if it were me, I'd take on a flyer on him before someone like Cabral Huff or Korey McCray.
