Brees got it done on the road in hostile territory more often this season, too. Only the stall-out in Dallas was the blemish. Mahomes on the other hand lost in Seattle tonight and in Los Angeles at midseason.
I saw that game and Mahomes didn't lose it. The KC atrocious defense did.
With that said, I believe Brees deserves to be firmly in the hunt for MVP even if he doesn't win it, but that he is not going to be in the hunt at all. All that will happen is that he MIGHT be at the ceremony and receive less than five votes.
That's the best he can hope for. That's the best he can ever hope for, no matter what. It's all he's ever been given.
