This is where I'm coming from. Right out of extra bases:
"LaRoche's impressive seconds half splits are "nice," Epstein said, but they were not a "key component" in the decision. Epstein believes playing at Fenway will help LaRoche, because his natural swing drives the ball to left-centerfield."

Even if he doesn't hit to left all the time, he's still a better power hitter than Kotchman. He's still a better 2nd half hitter than Kotchman. I think we're only arguing formalities because it doesn't matter if he naturally hits to left or not, but I'm still defending my point. The truth is, regardless of who's right in the me vs. Dipre and ORS ordeal, he's still a much better power hitter than Kotchman and I still feel uneasy about that trade.
So no matter what one person says or what a spray chart suggests, that won't change the uneasiness I feel about the trade. We can argue formalities all day but that won't change anything.
