Because in this scenario, we give the Rockets a prospect who helps their perimeter D without losing useful veterans, or existing prospects get some much needed rim protection, as well as keeping enough assets to pusrsue a Melo type scorer via trade. Granted both big names will be on expiring deals, as well as Rondo, I reckon a rotation of Rondo-Bradley-Melo-Sully-Asik as starters, with Green, Olynyk, Faverani, Pressey bringing positional and tactical versatility off the bench does well enough to become a mediul term contender.
