Since Jose is clearly the only one who BC and Co. are looking to trade and have made it very clear that a trade will be made only if it's beneficial, here's a proposal.
Raptors trade Jose Calderon, Ed Davis and two 2nd rounders to Utah for Paul Milsap and Earl Watson.
Trade is made on the condition that Milsap signs an extension.
Milsap bolsters the Raps front court and that's an understatement. Bargnani, Milsap, JV and Amir would make up one of the best front-courts. E Watson along with Lucas would form an average back up for Lowry. Not the same as Lowry/Jose and that's OK for now. It can be taken care of in the off-season as Watson becomes a FA.
In Jose, Jazz get a PG who's better than Mo Williams and can therefore start. If rumors are right, they were interested in Jose at the beginning of the off-season. Ed Davis is no Milsap but bolstering the PG position more than makes up for that. Besides Ed is a solid future back up if not a starter. Jose's contract expires at the end of the season which gives them the option of either re-signing him or not, depending on whether he(Jose) worked out or not.
Raptors will not have the financial flexibility that they would have if Jose remains and becomes a FA but for Milsap, I think it's worth it.
Obviously Raps will have to move Bargnani to Center to accommodate Milsap. Not his preferred position but we'll have a much more effective front court combination.
A line up of Lowry, Derozan, Fields, Milsap and Bargnani with Watson, Lucas, Ross, Klieza, Anderson, Amir, Gray and JV coming off the bench would be a formidable one. One that increases our chances of contending for a play-off spot by 3 games according to the trade-machine.
