I don't, because if he does another team is going to nab him quick. He's showing too much potential. CB-needy teams have their eyes on the waiver/PS wire, and you KNOW Jim Harbaugh is well aware of his brother's overcrowded backfield and the fact that one of them could help out his deficient secondary.
The way I see it, it's either a roster spot or to the IR with a phantom injury for Lee if we want to keep him.
