Melo losing weight doesn't mean that he will pass it more. Stoudemire might have improved his post game, but that doesn't mean that he will get the ball more. Felton and Kidd are not spot up shooters. I think that the Knicks have improved slightly but I doubt they reach 50 wins this year. I am thinking that it will be closer to 45 or so.
I agree with Orangello. Everything they improved on was not meaningful. The biggest reason why they weren't successful is Melo. Melo does whatever he wants. The greats understand that there offensive moves depends on how the defense is playing them. Melo is stuck in his own world on the court and just does whatever pops into his head. Melo losing weight is meaningless in terms of what caused them to be so bad last year.
Amare will greatly improve his game but I do think he will be getting the ball more now because of Felton and Kidd. Lin was a ball hog. Felton and Kidd will work at getting Amare the ball more.
I still do not think they will get into the top 3 in the East though. 4 at the highest but my guess is 5 or 6 in the East.
Teams that will be better than Knicks(No particular order)
Miami Heat
Boston Celtics (Younger talent and Courtney Lee will surprise a lot of people with his defense and scoring along with Jason Terry).
Indiana Pacers (Only better with playoff experience)
Philly (Bynum & Hawes together are going to surprise a lot of people and they have 3 point shooting now from J-Rich, D-Wright & Nick Young. Turner gets the ball in his hands which will make him better since Iggy(overrated) is gone.
Brooklyn Nets - This tough to say but I do think they will be better than the Knicks because of the balance on the court and D-Will & Joe Johnson understand playing the defense unlike Melo.
Teams looking on the outside in
Chicago Bulls - Nobody knows this one. I think they are bottom between 7-10 of the east. If Rose comes back in the last 2 months than things become more interesting
Bucks - After they got Ellis in the Bogut trade they went on a run and that was with Drew Gooden playing Center. They now have some shot blocking centers to pair with Ersan Ilyasova who had a break out year and will only get better.
Wizards - My gut tells my to say no way. But looking at them on paper they seem more balanced and talented. If John Wall can become efficient and if Nene and Okafor stay healthy than they could shock some people. Along with the Rookie Beal.
Hawks - Still making moves and if Horford comes back healthy he will get the ball more and they will be more efficient. But 7-10 also
Knicks are inbetween these groups of teams still. If Melo learns how to play the defense and pass at the right times and keep the defense guessing than the Knicks are contenders. But until that happens they will not be contending any time soon. I feel bad for anyone who has to play with Melo.
