Looking at things from CV's POV...
This is a debate that could go on forever and both sides can make great points but the way I see it is, you shouldn't be considered for the MVP Award if you are on a losing team.
Yes, Giancarlo Stanton is having a historic season for the Marlins but they have a losing record.
If you were to take Stanton off the Marlins, you still have a below .500 baseball team. Where is the value in that?
Guys like Paul Goldschmidt (Diamondbacks) and Nolan Arenado (Rockies) may not have as many home runs as Stanton, but both Goldschmidt and Arenado have higher batting averages, Arenado has more RBIs than Stanton (111 to 110 with Goldschmidt at 109), and the biggest thing is that both the Diamondbacks and Rockies both not only have winning records, they actually lead the N.L. wild card race.
Again, it isn't fair to Stanton because the other guys have a better all around team but the fact is he is only being considered for an MVP award because of his home runs. That's not fair either.
I think all sports should adopt what college football has and that is the Most Outstanding Player Award.
Giancarlo Stanton would absolutely deserve that award!
