Wade Phillips says it himself the weight hasn't affected him and he is just as athletic as before.
"He's going to run people down from behind, he's got to just keep doing what he's doing," Phillips said of Barwin. "He worked hard this offseason. He's fast, he's athletic."
"He went in, did such a great job last year, against really good people," defensive coordinator Wade Phillips said. "He was always playing against the left tackle in passing situations, most of the time. The sky's the limit for him. He's about 270 pounds and he's a really good athlete."
