This may be Tom Nalen?s last season in the NFL after a fantastic career in which the Broncos starting center garnered 5 Pro Bowl selections. "I'd be lying if I didn't say I didn't think about it," Nalen said. "I don't have a contract for next year. I don't know what's going to happen." "Tom was the anchor to our championship teams," Sundquist said. "We all know what he has meant to the success of the running game in the Mike Shanahan era."
