"It's obvious that Richard's got a lot of free time on his hands," Carroll told reporters, via NFL.com.
"I haven't read one word he said. I just see the pictures and the mouth open and I know what's going on. He's having fun with it. Richard knows what he's doing. He's having fun playing with the whole thing. And he had a tremendous season and a very, very good last season, so he's got something to stand on right now. It's better (than) when he used to talk when he didn't."
While Carroll didn't exactly agree with Sherman's best corner in the league claim, and does understand why "Mr. Revis" might be a little peeved at Richard's boasts, he said "I think [Sherman's] a great corner. I think he's playing tremendous football. I think not enough people know about him yet, although he's working on that. ... I've never known how you scale the very best corner, you know, but he's up there in consideration."
