Yeah. A few years ago when the Celtics were a pseudo-contender, the team was on the national radar and Rondo was putting up some juicy stats... it resulted in some all-star appearances. His body didn't hold up, though. He's an injury prone guard who can still probably help a good team when healthy, but his best days are well behind him.
That doesn't take anything away from what Rondo was able to do from 2009-12. He was a key part of keeping this team relevant as the star talent faded and our window closed. In terms of Celtic greats history will remember him on a par with Antoine Walker... maybe slightly higher, because he had an additional all-star appearance and he was a role player on a championship in Boston instead of Miami.
