I don't really know why you would say that. I haven't seen any definitive proof that Rolie is a way better keyboardist than Cain. Please provide a video or something that proves your point.

Every song from the Rolie era albums that I have seen Cain play, he seems to replicate verbatim so what are you basing your statement on?

Not to mention Cain is 50 times the songwriter, so even if you are right, I would take Cain over Rolie any day for his ability to write a hit song.
