You add him to Wall & Beal they'll challenge in the east.
A deal revolving around Otto Porter,fillers and draft picks could be enticing for both sides.
Melo grew up in the DC area which is close enough to NYC so his wife & kid don't necessarily have to move.
Just a thought
Here's a blockbuster which works salary wise:
Knicks trade:
Melo
O'quinn
Holiday
Lance Thomas
Ndour
To Wizards for:
Otto Porter
Kelly Obree
Trey Burke
Nicholson
Mahamini
Draft pick
Washington is a serious team--I wouldnt trade Porter and Oubre--come on??????? This team can give Cleveland trouble as is. 2nd best team in the east imho.
Wizards were hoping to sign KD but Melo is not a shabby consolation.
Wall, Beal, & Melo is a legit big 3.
As for the Knicks, Otto Porter will only get better and would fit in perfectly at the 3 with Porzingis & Hernangomez flip-flopping between the 4 & 5.
