Secondly, Rondo is showing C's glimpses of the future. Where he single-handedly dismantled the Cavaliers in 2010. His shooting is coming around. 6 years into his NBA career, Rondo has a lot of room to improve as a player. Last but not least, Sam Presti has gotten the better of Danny Ainge. I would advice DA to stay far away from Sam Presti. Last time those two made a deal, Celtics got fleeced.
If the future is a place where Rondo will put up massive fantasy stats, but we're going to lose, ship him out of town right away. Someone like Mo williams can do that for a fraction of the cost
Rondo has been asked to be the alpha dog this season, and so far he hasn't gotten it done. The Big 3 may not be viable first options anymore -- but they're still a pretty good supporting cast. Probably better than anything we will be able to put around Rondo for a while.
Rondo's the one who hasn't been getting it done?
And you really think the squad we have out there is great supporting cast? JO has played like the worst offensive player in the league and his defense has been slow and ineffective. KG has been extremely disappointing to start. We get nothing from the 3 position each night.
Getting it done = getting a win. So yeah, with this supporting cast Rondo hasn't been getting it done.
And if you think you'll pick up a bunch of roleplayers that will contribute better than Garnet, Allen and Pierce will -- you're delusional.
Pierce/Garnet/Allen on their last legs > average league role-player.
So yeah. Rondo has been a great piece, and his contribution has been amazing when the team didn't live and die by it. But I'm yet to see any indication that he can put the team on his back and carry it to wins with just average supporting cast (see Kobe, Durant in their prime, or Tom Brady in other sports).
In this sense, while he's great to have, you either have to acquire a true franchise player, or ship him for one. I fully understand the management's attempts to achieve this, especially given that we'll probably only be able to get a very-good-but-not-great player through free agency next season.
