The Houston Rockets are in the middle of retooling their role players. After losing both Trevor Ariza and Luc Mbah a Moute to free agency, the perimeter defense and 3-point shooting of the team needs a bit of work.
One option that has come up repeatedly throughout the process is Carmelo Anthony. He was heavily rumored to have been interested in the Rockets last summer, and vice versa. When he became available again, both sides seem to want this to finally happen.
That may solve some of the offense lost by those two guys, but the Rockets still need to play some defense.
