I think Rondo left a bad taste in the mouths of Steven's and Ainge when he mentioned not trying on defense consistently. For that reason I just do not see Rondo returning, ever. And that sucks because I am a huge Rondo fan.
While I understand that particular concern, there is also a difference between backing up Kyrie for the minimum and being the all-star leader of a young (and tanking) team. Rondo has been on several teams of different calibers since leaving Boston - I think he now has a better perception of the NBA landscape and would relish the opportunity to play with a championship contender...especially in Boston (given his glowing post-game comments of the team/organization).
I would hope Stevens/DA would understand that Rondo isn't the same 'punk' that he used to be and having an engaged veteran talent like him off the bench would be huge.
I am sure Stevens and especially Ainge know exactly who Rondo is now and how he might fit here. My guess is their previous experience means he won't be here.
Rondo didn't try on defense then admitted he was doing it.
Rondo left the team without approval on a west coast trip to have a birthday party.
Rondo threw a bottle at a television set and broke it in the middle of a team meeting.
Rondo was a massive dick in the locker room to team mates for most of his time here.
Rondo burned down the Celtic bridge. He won't be back. But if I am wrong I will be the happiest guy on this site. I think after BBallTim I was this site's biggest Rondo schill.
Heck if getting Rondo back gets BballTim to return, it would be worth it.
