With Daniels in the fold, and Marbury on the horizon, I tend to think Wafer is worth the risk.
Yes, he has only done it for one season, but Daniels can backup both wing positions if he flops. I think he will improve with the ball movement, work ethic and leadership on this squad.
Yes, he had a falling out with his coach last season, but that will not happen with the leadership on our roster.
Finally, I see him as a potential long term replacement for Ray - clearly a step down - with the ability to be a very solid starter next to Rondo and Perkins as we transition to the Celtics' next stage.
