The Celtics are trying to trade him while his stock is high. Not only is he a little girl and complains too damn much... I think the Celtics fear that once the big 3 is blown up after this season is over, Rondo might struggle next season and that will lower his stock. A lot of people believe, my self included, that Rondo plays better because of the system he's in and the players he has around him. Maybe the Celtics agree with that a little and want to trade him now. Well they've wanted to trade him for months now... but with the trade deadline nearing, I can see why they'd be pushing.
Plus.. let's look at this hypothetically. Rondo is 26 years old and believed to be a top 5 PG by many. Deron Williams is 27 and believed to be the 3rd best PG by many. RW is considered to be the 4th, maybe 5th by a lot of people. Do you think the Celtics would aggressively be trying to trade either of those 2 players because they don't want to build around them? Fuck no. So there's definitely something there with Rondo
but I'm gonna laugh if every deal gets rejected or falls through and the Celtics start saying "We love Rondo. We were just exploring our options and we really do want him back."
