I don't think people need to worry about Shermin not knowing what to do with his time. Nor do they have to worry about him not being smart about this. The guy is working on his MBA from Stanford. They aren't just letting anyone in there.
As for the millionaire comment, Sherman is brining in less than half a mill. The guy is hungry and hasn't cried about a new contract every 3 games like Reevis has. Heck Reevis is making top dollar and still crying about being underpaid, while Sherman is letting his play work out his new contract.
I like Sherman. I think he is right. His game says he is on the door step of being the best and he is just knocking. Reevis didn't play last year so who knows what he will be like.
