The Rockets still likely want a backup power forward. Even if Houston does acquire Carmelo Anthony, that position is still a desire for the team. Would Boris Diaw fit that role for the team? He definitely brings veteran leadership and championship experience, but would his play be good enough for the Rockets?
Experience
If for nothing else, the Rockets should look to sign Boris Diaw due to his playoff experience. He went to two NBA Finals whenever he was a member of the San Antonio Spurs and was a decent bench player for them.
