Kotchman was the worst of them.
We're not discussing whether Kotchman is worse than other 1B's. We're discussing whether he's worse than other M's.

That said, any flyball hitter is going to hit into fewer GIDP's; Griffey's rate was 1/3 Kotchman's last year.
Bradley's GIDP rate was 25% lower than Kotchman's and that's before you isolate to the RHP's that Kotchman will face (Bradley will get out of the LH box in those games, so should hit #3 vs RHP's if GIDP's is the deciding factor).
Kotchman is a slow guy who hits tons of groundballs. I think this one is pretty straightforward; GIDP evasion is not a reason to hit Kotch behind the two SB stars.
