Yes they did jeff... Joe montana's back was so bad they thought his career might be done at 30. He suffered a horrible concussion in the 86 playoff game and broke his wrist. He missed 15 games in his last year with the 49ers. Young had a history of concussions that caused him to quit just one season after making the probowl. I'm not suggesting mcnair will be winning MVPs beyond age 35. All i'm suggesting is that he has some good football left in him at 33 and 34. With the titans working so hard to build a good team why would we want to dump the guy who has been the guts of this team? Every aspect of this offense can be better in 2006. The o-line, the running game, the WR. Maybe we draft dbrick to improve the line even more. Maybe we trade down and draft deangelo williams. Mcnair is a better than average nfl QB and should be better than average for at least 2 more seasons.
