I'm not sure why anyone should feel sorry for Rondo. He was always an athletically dependent player who we waited for years to develop at the very least a respectable outside game, but that never happened. He never game consistent effort, as Pierce recently alluded to, and as a result our overall team play was erratic since the middle of the 2009-10 season. He also could've committed to us long term by signing an extension, but held out for more money and/or greener pastures (pun intended).
I'm sure years down the line Rondo will regret some of those decisions.
Rondo also had his legion of adoring fans here that were quick to give him a free pass. How many times did we hear "he's still not recovered from an ACL injury", "he's playing with inferior teammates", "Coach (insert name here) isn't using him correctly", or "wait until the playoffs" to excuse poor performances?
He was called a superstar and fans were irate over the lack of perceived value we received for a "player of his caliber". You can go back to that trade thread as a lot of fans wanted Ainge's head on a platter.
(good read in retrospect)
http://forums.celticsblog.com/index.php?topic=74828.0Fast forward a few months, and suddenly Ainge doesn't seem so dumb, the trade doesn't seem so bad, Rondo doesn't seem so good, and his fans aren't defending him so feverishly.
