The guy is a solid corner now, he's just not what he used to be and has been fragile the past two years. But he's not wrong for taking his time in this market. I don't know that any team would pass on a good corner addition, and the Colts for example are desperate, moreso than the Rams, so maybe taking his time gets him a big deal from Indy.
The big deal is what I'd avoid with him. He needs to be a little bit hungry IMO, so I'd go with a short term deal where he gets his mojo back with the Rams and then rolls on to another team for his big retirement deal.
