Let's list them out?
Option 1: Trading Tyson Chandler and Raymond Felton for Jose Calderon, Shane Larkin, Samuel Dalembert, Wayne Ellington, and two second-round picks (Cleanthony Early and the Greek Freak's brother).
It didn't seem like a bad deal at the time. Tyson Chandler wanted out of New York and looked bad last year, Felton was a cancer off the court and a terrible player on the court, and Calderon was a pass-first PG, Larkin was a young player with potential, Dalembert might be able to rebound and defend still, and Ellington was a throw-in. Not that bad. Instead, Tyson Chandler returns to form, Calderon sucks and struggles with injuries, AND, to top it all off, this move gave them 2.8 million dollars less in cap room for 2015. Calderon is also under contract through the 2016-17 NBA season, so we're stuck with him at point guard. This trade did get the Knicks two second-rounders with some potential, but the biggest question remains - if Phil had held off and traded Chandler later on in the season, could he have gotten something better for him? (Dragic, Reggie Jackson, maybe?)
Option 2: Trading J.R. Smith and Iman Shumpert for Lou Amundson, Lance Thomas, Alex Kirk, and a 2nd rounder in the 2019 Draft.
This one actually made some sense. We all loved Shump, but this one was about getting J.R's contract off the books and getting rid of the 6.4 million dollars in cap space he was taking up. To do that, we had to get rid of Shump. However, this looks bad for the Knicks now for the simple fact that J.R. and Shump are playing very well in Cleveland, and the bigger question is whether they could have gotten more back in return from the Cavaliers. A point of comparison may be the Timofey Mozgov trade - the Cavaliers gave up two first-round picks to get him, but Phil couldn't get one for J.R.
Option 3: Re-signing Carmelo Anthony to a 5 year, 124 million dollar deal.
This one doesn't look so good now either. A few months after he re-signs with New York, Carmelo undergoes surgery on his left knee. While he is expected to be ready to play by training camp in the Fall, Carmelo stirred headlines when he mentioned that he will be injury free, but, at the same time, he "doesn't think he'll ever be a hundred percent." So the Knicks signed a player through his age 35 season, and in year one of the contract, he's already claiming that he'll never play to the level he originally did.
All three of these moves are questionable, but some of them have some silver lining. In your opinion, which move is the worst one?
