Honestly, I think the whole "attitude problem" with Rondo is way too freaking overblown. blink, you're absolutely right that all the young players love Rondo. He's the one that tries to get the team together (remember last offseason's LA gathering organized by Rondo?), and tries to make everybody feel welcome. In the documentary ESPN did on the Celtics, Bradley said that after his tough rookie year, it was Rondo who kept pushing him on.
The ONLY halfway legitimate issue Rondo has created that I'll believe is with Ray Allen, but that's only cause Allen was a bona fide drama queen. And this offseason, the media tried spinning a whole story about how Rondo might've been the reason Doc left, but I highly doubt that, because every story up to this offseason has shown how much respect Doc and Rondo hold for each other.
