Molina will win GGs, but not for a few years when he's proved himself as being one of the best in the game.
As for Yadi's hitting, if we ever got .280/20/90 out of him, I would be ecstatic. I think that's stretching it, though. I would bet that an average, mature Yadi hits .270s/teens/60-70 every year. Couple that with his fantastic arm, and you have one of the most underrated players in baseball (from a non-fantasy standpoint).
