Sounds like Kevin Martin isn't happy in Houston, which led me to think about trying to get him in a package with Kyle Lowry. Maybe we offer a package of Wesley Matthews, Nolan Smith, and our first round pick (potentially the Nets pick, if that was what it took).
He is only under contract for one more year, so you don't lose a whole lot of flexibility, and if it doesn't work out you can look to trade him at next years deadline. You then look to fill your hole at the center spot with whichever pick you have left. Drummond hopefully if you have the Nets pick (he is most likely gone), or Meyers Leonard if you have our pick.
Drummond or Leonard/Przybilla/FA
I think that is a pretty good roster for next year, while still providing you the flexibility to do things mid-season, or next off season. Obvious question marks are backup PG and the center spot.
