Kurt Thomas seems to be the only big left on the market worth spending any money on, and I think he'd be a good pickup - but that would likely mean the end of BBD's career in Boston. You wouldn't have Powe, BBD, and KT all on the roster as backups, there's too much redundancy. Maybe you could trade BBD, a 2nd rounder, and Scal (for salary ballast, only two years left at this point) in a sign-and-trade for one of the better PGs left on the market (like Dooling), then split the MLE between KT and House. I don't know, KT would absolutely be helpful to us next year but it's going to take most of the MLE to get him, and you'd still like to flesh out the bench some more.
