Rodgers and Brees are in a 1 year tie in my opinion. The tie breaker is time invested. Brees has done it longer and proven the pedigree to deserve the MVP. If one or the other had a big lead over everyone else, then fine, but this is really a tie.
I know it's supposed to be about "this year", but if that were the case there were years that some other MVP's wouldn't have won it in similar tie situations. Let's be honest.
Look at the list for past MVPs and check out the year others in the league had those years:

2009 stands out to me the biggest. Drew had an incredible year and was on an incredible team, with considerably better stats than Manning, but Manning won because of pedigree.
Brees deserves this MVP, he's earned it this year and past years. Rodgers will earn it if he can keep doing this.
