I say Minnesota beats Sac, simply because I actually think they'll be better without Hudson and Wally. When those two came back, the Wolves seemed to face problems similar to although not quite as severe as Sac did when Webber came back. With them out, Minnesota should be able to play at the level they played at before, when they were one of the top three teams in the league.
I'll go with Pistons in 5 over Jersey. Tayshaun Prince is on FIRE, and I expect Rasheed to have his way with K-Mart, especially if his outside shot's falling.
