We have no use for a high volume scorer even on the second unit. With the exception of the game without Daniels, the 2nd unit gets awesome quality shots. We already have enough offense.
Also, AI is not nearly the player he was two years ago. Short guards who can't shoot don't age gracefully like Nash, Ray Allen, and Reggie Miller. The wheels just fall off. AI's wheels have fallen off. He never could shoot well, and now he struggles to finish at the rim as well. He would be useless to us.
