Re: AL mvp....
I think it's worth noting that WAR is not technically "best player" but rather best player relative to his position.
If you truly wanted "best player" you'd have to remove the positional adjustments from the equation.
Now, perhaps that makes it a good metric to determine "value" but I do think there's a difference between best player and 'most valuable.'
