I'll say it again, spending 8-10 million on a guy who will play behind Pierce (already under contract) is a ridiculously dumb idea.
Wdleehi is correct, you need to get your core together FIRST. Otherwise you get stuck above the cap and you don't have enough to build around. Worry about role players that will down the road replace Pierce DOWN THE ROAD.
It's not like we're even talking about wasting cap space on someone to replace Ray or KG who are actually coming off the books. Why is this even a discussion?
