I would rather have White, JR Smith, and some other players than overpaying for Fields.
He just won't have much minutes given to him with our team upgraded.
We don't need another bad contract, he fits in with Toronto much better than with us.
It would be like JJ's contract over again, on Fields 3rd year if we tried to move him.
Only reason why we might consider keeping him is to keep Jeremy Lin and his BFF happy?
We have Melo on this team at the same position, with Euro draft rights that play the same position if people really feel those guys could contribute.
Just no room for him to play, especially at that price to keep him.
Iman/JR/White
Melo/Novak/WHite
add the euro players in there somewhere, what will we do with Fields contract in 1-2 years?
Would his contract be a liability or an asset, will depend on how he performs.
Without much playing time, I think we all know what is the likely answer to the question...
JR Smith is most likely going to opt out next year or we going to give him 7m a year or more to keep JR happy if he proves himself, next year?
Just my opinion, don't hold it against me if they match, and he has a great year. 
After all, it isn't our $, its Dolan's, and it comes out of the ticket prices/vendors/ and networks/cables/direct tv etc.
With Linsanity back, if he is the real deal, they will get a huge bonus on their stock prices *hedge funds*, advertisements, ticket sales, jersey sales, and etc....
