746 career road OPS vs 738 Home
Is he hitting less HRs at Home? Yes, maybe his home stadiums hurt him slightly in this regard. However hes hitting more doubles on the road and his Isop is .012 points lower.
Kotchman doesn't fit the profile of a guy that I think was hurt meaningfully by his home parks. Safeco is a better fit for his HR profile than Anaheim, but worse for his spray chart.
To put it another way, does it really change your evaluation of the guy if hes got a career 742 OPS and you think he deserved 750?
Either way, hes not the kind of bat you want at 1B (unless you think he can breakout).
