Yeah bad/good defense in LF is definitely the same as the difference between great/epicly bad defense at SS/3B. I don't trust defensive metrics that much, which is why I regress those numbers more than the offensive #s, but even with taking the offensive #s at a greater weight because of this, it's still a wash. It's insane to just toss out Tulowitzki's home numbers because he plays in Coors. I don't know how many times I can re-post the same thing, but every time the topic of a Colorado player or pick your player playing in a hitter's park, people seem to want to just take his road #s and say, there's his true hitting level. Beyond the Coors hangover effect that has been studied, there's the fact that hitters hit better at home period. There was a 24 point difference in OPS between home/road games for the NL this year. (Braun was 80 points better at home) Let's also add in the fact that Tulowitzki doesn't get to play any road games at Coors field. Again, I don't think it's a slam dunk for Tulo, but I would've voted for him.
