Bears tight end Greg Olsen is content with his role on the team and wants to remain in Chicago. There has been speculation that he could be traded because he's not a good fit in new offensive coordinator Mike Martz's system. No tight end under Martz has caught more than 38 passes in a season. He led Chicago with 60 catches in 2009 and his blocked has been suspect. "So far I have a great feeling about my role this year," Olsen tweeted Friday. "I have no desire to play anywhere but in Chicago. "That was purely media speculation."
