His inability to stay healthy is why the rest of the world underrates him. His ability when healthy is not something we are overrating, his performance speaks for itself, he was nothing short of an unrecognized all pro caliber player, unfortunately he has had BAD injuries that linger into his playing time and have obvious effects. That lisfranc haunted him for over a year. But 2013-2014 was perhaps the most impressive stretch of cb play since revis from 09-10, the list of opponents would make fans of any team shit their pants, yet jimmy lined em all up and knocked em all down with authority. and before his injury in 2016 he was back to form and absolutely blanking elite receivers.
I may give him a lot of leeway when he is injured and struggling, but that doesn't mean I'm overrating his ability. When he's healthy he is a top 5 corner who never got the recognition
