Daniel Thomas saw his rookie year with the Dolphins marred by injury, but he's prepared to take a step forward in his second season. "I know I've gotten better," Thomas told the Miami Herald. "The injuries affected me a lot last year. They messed my mind up. I lost the confidence I had. I didn't have the same burst I had earlier (in the season)." A second-round pick in 2011, Thomas was penciled in as the starter, until the team acquired Reggie Bush.
