The Cubs being in 1st place most likely will have nothing at all to do with the MVP race assuming the Brewers make the playoffs. They do consider playoff vs non playoff, but not seeding. Braun beat Kemp out because of some big HR's down the stretch that got the Brewers in the playoffs for the first time in forever and his battle for the batting title that went all the way to the final day of the season. Part of it was also Kemp playing on the west coast so nobody seeing him, same reason Trout doesn't have more MVPs. That one was narrative driven, not team driven. The same way if Yelich beats Baez it is likely because of how hot he got late and the double cycle.
