Dolphins linebacker Kevin Burnett isn't happy with his performance so far this season. "I haven't done enough to help my team," Burnett said. "A season is made of 1,000 plays, and I've got 830 more to go. But it has to happen now. At some point, you have to show flashes of it. I don't want to live on potential and not production." The Dolphins viewed Burnett as an upgrade to Channing Crowder, who abruptly retired after a six-year career when the team cut him in late July.
