I was surprised to discover that the NFL does not have clearly defined criteria for the MVP award. So, it is, to some extent, left to each voter to decide whether it goes to the player who meant the most to the success of a very successful team or to the player whose overall quality of play was the greatest. In recent years, it certainly seems to have gone to the player who met the "overall quality of play" criterion.
So, four thoughts:
1) If "overall quality of play" is the criterion, then, barring a season-ending injury or an unimagineable finish to the season, it is impossible that the award goes to anyone but Brady.
2) If the criterion (unfairly IMO) shifts to "meant the most to the success of a very successful team," then I guess those who want to punish the Patriots' organization for Spygate would argue that Favre has fewer weapons than TB and would try to give the award to him.
3) However, while I know that it's impossible to underestimate the media's dishonesty and lack of ethics, nonetheless I just don't see the media cooking up a reason to deny Brady the MVP, no matter how much they might profess to hate BB and the Patriots organization, especially, as now seems likely, Brady breaks Manning's single season TD record and enables Moss to break Rice's record.
4) The media love a "horse race," so they're creating one by suggesting that Favre or Moss or Romo might get the award.
