This isn't a super big deal, but it is something to certainly monitor. Any time someone has surgery it should be looked at carefully and obviously there's a few problems with the knee and you never know when those problems may arise again, if they ever do. Missing some of training camp and some of the preseason games is kinda of a big deal too. I know he's Peyton Manning and he has good chemistry with his backs and receivers, but those reps that he's missing are chances to further develop that chemistry. I think it'll take until the Colts' bye week, week 4, for the Colts offense and Peyton to be in full rythmn.
