Yeah, I heard Aaron say the pretty much same thing in a recent TV interview.
that's a tough call since the league is so much more QB friendly than it was before. Many QBs today wouldn't be successful if the rules were the same as they were in the days of bradshaw, stabler, and even montana. Before, CBs could do more to stop receivers and you could clobber a QB; now, if you look at a QB too long, it's a penalty.
