Well, West's return should help. That's not to say he can play the 3, but his return to the 2 should allow Wafer to play even more at the 3 and let Ray slide to the 3 at times (not ideal, but something we've done before).
With Pierce, it depends on the injuries. There are some injuries that can get worse and others that just take longer to heal if you play through them. If he has the latter, it sucks, but we can deal. If he has the former, I suppose we have to sit him.
We'll make the playoffs no matter what at this point, and while I'd like to keep homecourt, a healthy Pierce is even more important.
