I'm with Mxy on that one. I don't think Gordon is clearly better than Rip. I'd say they're about equal, talent-wise. Gordon has a better offensive game because he can handle the ball and shoot the 3 a bit better, but Rip's defense is leaps and bounds better than Gordon's. Rip has a better mid-range game. I'd bet Rip has better endurance. It really comes down to who fits the offense better, and Gordon may fit better with Stuckey, were Rip would fit better with distributing PGs. We'll have to wait and see.
I'd say, in the Eastern Conference, if you put Rip on a team with a pass-happy PG he's back to All-Star form (too many good SGs in the west).
