We are stuck with our roster. I for one am not completely dissatisfied. I would have liked an additional back court player but I'm quite content with not forfeiting assets (pick or players).
I think a few change would be quite beneficial to the team without completely killing chemistry and moral.

I'm not quite sure of how to rearrange the rotations but a back court of galo and calderon or grant and afflalo would be nice.
At least anything that puts calderon at the 2. He could be useful at the SG. He would not be as exposed on defense.
I looked at http://espn.go.com/nba/players/_/position/sg. There are difficult fits on defense in the list but not as much as against the PG of the league. He would have a facilitator and shooter's role. Exactly his
strengths.

Afflalo on the bench would give a much need offensive spark in the 2nd unit. One iso player per unit.
It would balance the rotations IMO.
What would you envision?

Stretch Calderon and bring in both Fredette and Thenasty from the D-League to solidify our back court. Offense-Defense. Keeping Nose and Sasha on the roster is counterproductive

This would be rotation right now:

Lopez/Porzingis/Anthony/Galloway/Grant (9 minutes)
Porzingis/Williams/Anthony/Afflalo/Galloway (3 minutes)
Lopez/Williams/Thomas/Afflalo/Calderon (5 minutes)
Porzingis or Lopez/Anthony/Thomas or Williams/Afflalo or Jose/Galloway or Grant (7 minutes)
or = Alternate between the two in the stretch

If you think about it, the starters don't really play well on a consistent basis to start the halves. So why not just give others a chance to start, and bring the veterans off the bench. If the veterans like AA, Jose play well, then you close with them.
