New Colts running back Trent Richardson intimated that he has noticed a difference in the locker room atmosphere between the Browns and Colts, ESPN is reporting. Richardson expressed his excitement on Thursday over joining the team that traded for him.

"Just being in the locker room for these couple hours, it's been a big change," he said. "They're happy to come to work and they're ready to go."

Chuck Pagano said Thursday that Richardson will play as much as he can handle Sunday against San Francisco.
