With Courtney Lee apparently traded, I would not be surprised to see the following go down.
Humphries, Wallace and either Brooks or Crawford to the Knicks for Stoudemire and Iman Shumpert.
It would make a lot of sense for the Knicks.
Chandler / Bargnani
Humphries /
Melo / Wallace
Jr Smith / Hardaway Jr. / Prigioni
Felton / Crawford / Udrih
The Knicks would still need to sign another PF but this would make them much more complete. They hold onto Wallace for an extra year at $10 Mil but may be able to buy him out or trade him after next season.
In the meantime he provides much needed back up for Melo and possibly at the three. After Chandler they have nothing substantial up front. Humphries would fit very well and he'd also come off the books so they could go after another big shot at PF in the off season.
For Boston, we dump Wallace's contract and get Shumpert to solidify a nice backcourt - he'd be a very good back up for Bradley - tough D, can shoot threes and is physical at 6' 5" when Bradley's getting muscled. We them focus our draft picks and other moves on front court help.
