I've offerered this in the past, but it's worth repeating.
MLB needs a third "major" award, at the same level of Cy Young and MVP. For the sake of argument, call it the "Babe Ruth Award", or the "Ted Williams Award", or the "Willie Mays Award". Whatever. Much like the CYA, it would go to the best hitter in the league. That then frees up the MVP to go to the player who most contributed to his team's success.
This then solves two problems: (1) the success of the player's team, or whether or not they make the playoffs, is irrelevent to the discussion for the new award . . . much like Steve Carlton's CYA in 1972, if the player was arguably the best hitter in the league, it doesn't matter if his team loses 100 games; and (2) it removes the bias against pitchers ("because they have their own award") from the MVP discussion, because now bother hitters AND pitchers have their own awards separate and distinct from MVP.
If this was the case, then one could then argue that Cabrera's Triple Crown (assuming he hangs on for the next two days) gives him the "hitter" award, and Trout gets the MVP.
