Gooden has the best stats of these guys, but he doesn't really scare me. Cleveland didn't really seem to miss him all that much after they traded him for Ben Wallace (the conventional wisdom at the time was that the Big Ben trade was a steal from Cleveland's perspective). Better than Mikki Moore? Sure, but I'm more confident Moore will learn the defense quickly; my recollection of the Gooden chatter from last year was that he'd been in Cleveland for four years but hadn't figured out the rotations yet.
My hope for Moore is that he's at least long enough where he'll be able to put a hand in the face of Big Z (and hopefully Pau).
Still, whether we beat Cleveland or they beat us depends mostly on
1. Whether Pierce can slow down LeBron
2. Whether the officials will LET Pierce slow down LeBron
3. Whether Mo Williams destroys Ray Allen, Eddie Money, Starbury, and everyone else we put on him
This isn't a team we win or lose to because of the end of our respective rotations.
