You mean, any time ESPN says something negative about the Yankees, it's because of an anti-Yankees bias? Oh yes, because in the eyes of a Yankees fan, everyone is biased against the Yankees -- you'll see the umpires bias against the Yankees mentioned in every thread on a Yankees board. If the MLB and ESPN didn't care about ratings -- then yeah, it'd be a possibility that they'd show a bias against the largest market -- but they do.
Now, with that aside, it's too early to pick an MVP. Last season, Vlad got it a lot because of what he did late in the season in carrying his team -- who knows if someone will do the same this year.
