Dominique Rodgers-Cromartie's work ethic

"I was always a fast guy, but I have to be moving, I need momentum to get going," said the 6-foot, 200-pound Jenkins. "But now I'm working on coming off the start and getting more power so I can get a better 40."

I don't think Jenkins did himself any favors by admitting the above statement. Aren't these guys supposed to be selling their good qualities? Seems like a stupid thing to say...
