I love this discussion coming in from the fanposts. What do you think? -jbopp

What defines a MVP? 

Batting average, on-base%, slugging%, HRs, RBIs, SB, runs, etc?

WAR, wRC+, wOBA, etc?

Fielding percentage, errors, assists, putouts?

Advanced fielding and base-running metrics?

Is your team a playoff contender?

Big market/ small market?

The problem is no one seems to agree. Fans disagree with voters and voters disagree with fans. I'm curious to hear what the statistically inclined community has to say about this. So let's discuss what makes a player the most valuable to his team and which two players currently should be the front runners for the AL and NL MVP races.
