simple quick fix is - Bargani and Calderon for Pau, Ebanks, and Blake
Bargs would hit the shots that Pau misses. He has a better ts% this year and is better from mid and 3 to open it up for Dwight.
Calderon could start from day one for Nash, run the system, provide the shooting, and then would be willing of move to the bench as he has always been part of a pg tandem with Ford/Lowry.
Jose could get the bench looks when Nash returns. Bargani also unlike Pau isn't a 5 so you can give Jamison backup PF duty full time and Hill can be the backup 5 full time and next to Bargani to maximize his rebounding when Dwight sits. Then the rest of the bench could be Meeks and Morris playing small against second units as both guys are around 6 4 / 6 5 which is what Raja Bell was in Phoenix when he used to play 3 with Barbosa at 2. In the meantime Duhon could play with them to Nash gets fully healthy, and Sacre can round out the bench.
Ebanks being added frees up a roster spot for mid March when guys get cut, a d league call up like CDR, if Tracy wants to return from China, if we see a need for Kenyon, or if Pietrius decides to play for pennies finally
That is the move we need to make to make the offense work the way Dantonis O is supposed to be ran without a drop off, give Dwight spacing he is used to from the 1 in and 4 out, and truly save the nos of this efficient Kobe we have had this year for the real season aka playoffs
