Actually, I think that ole Les is very smart. He just has a strange way of communicating when he is in front of a camera. Eating grass might do that to a person. Les was lucky in that he inherited a wealth of talent and a great team when he took over at LSU. Not sure he could have built that team from nothing, but that doesn't matter at this point. LSU is a great team and will remain a threat in the future.
Saban is a totally different personality and is strictly business. No time for foolishness.
