Re: Stubbs vs. Votto
I still like Curtis Granderson as a comp for Stubbs. I think Stubbs will trade some of those homers for doubles and triples, but would not at all be surprised to see him maintain something like a .270/.340/.440 line. I think he's got a bit more power than Gutierrez. In any event, he only needs to put up something like a .700 OPS to be a solid addition to the team thanks to the quality of his defense.
Games are won on run differential -- scoring more than your opponent. Runs are runs, scored or prevented they all count the same. Worry about scoring more and allowing fewer, not which positions contribute to which side of the equation or how "consistent" you are at your current level of performance.
