I don't think Aaron Rodgers is overrated, he's a slamdunk HOF'er who, in his peak, was as good or better than anyone else who's ever played the position. But he's also a total schmuck, weirdo, horsefeathers, and he had more than a couple poor playoff performances. Like the '85 Bears, he almost certainly "should" have won more Super Bowls than he did.
He's a top 5 QB all time though. (This is somewhat arguable given how hard it is to compare players across eras and rule changes. I could accept an argument he's not top 5, but I couldn't accept an argument he isn't in the top 10 QBs all time, no matter how you're evaluating era differences)
