Now before you laugh at me and call me ignorant, hear me out. Carmelo wants out of New York, and the Knicks know that. They know no matter what Carmelo is going to walk after this season. And this season may already be lost for the Knicks. So the Knicks know they need to get something for him now or they will walk away empty handed. This may make them desperate, and may make them sell for less than he is worth.
Carmelo has expressed interest in the past that he wants to play with Rajon Rondo. Bringing in Carmelo will not only bring in one of the best scorers in the NBA and make the Celtics a legitimate threat in the East for years to come, but it will also keep Rajon Rondo on board. It will show Rondo this team wants to compete and win championships. A duel threat like Rondo and Carmelo could be lethal.
The East may get a lot weaker after this year. LeBron is a free agent and he may walk away from the Heat, ending their reign of dominance. Sure he may stay in the Conference (Chicago) but he may head out west. Either way this is good news for all Eastern Conference teams. And even if LeBron stays with Miami, if the Celtics have Carmelo, Rondo, and whoever they draft this year with what will most likely be a top 13 pick.
The only downside to this is the Celtics will most likely have to ship away Jeff Green and a few future draft picks (most likely some of the picks they acquired from the Nets). But to add one of the best scorers in the NBA, I say do it. I know Carmelo has not had the best attitude in the past, but with a new team, that has a historic background, and a young coach, I think that will change. If I was Danny Ainge, I would at least consider this deal.
