The fact that he took the depleted Pats team to the AFC Championship/Super Bowl 3 Years in a row shows me that he is just as dominant as ever, if not more. Unfortunately, he's pretty much asked to carry that entire team by himself. But hey, it's easy to hate on Tom. I wouldn't be surprised if the same happens with Russell when everyone jumps onto the next bandwagon.
And RBs are not put under nearly as much criticism as QBs. That's my guess as to why AP hasn't been dealt the same cards this time around. Either way, both are deserving of top spots.
