Well, I think having Wafer backup Pierce in the short term is OK. It's not ideal, but if we can survive games with Baby and Harangody playing together at the 4/5, we can survive 10-15 mpg of Wafer at the 3.
I don't, however, like it for the playoffs.
If Danny isn't sure that Marquis can get back for the playoffs, he really needs to make a move.
The only other scenario I could see working would be to work a rotation where KG is manning the 3 when Pierce is out. Is it ideal? No. But while people can talk about KG losing a step all they want, he could still probably defend the 3 better than most backups in this league.
