Best player is naturally the most valuable. The parsing of the name of the award is perhaps the dumbest part of every baseball season. I really wish people would understand that "Most Valuable Player" is just a fancy way of saying "The Best Player this Season." That's just like, um, your opinion, man. History has clearly shown this is not the case. Big contributors from the pennant winning teams have many more MVP wins than the "best player", whether or not it should be the case of course is the point of this debate, but it is a debate and it is not settled. Does seem to be evolving more and more to "best player this season" but that is a relatively novel interpretation. So would you have given the '82 WS MVP to Robin Yount instead of one of the Cardinals?
