I also believe that if the cheatahs can get their oline back to what it used to be, then bradys replacement unless he is a bust , will still do well. Of course that's a big if, since the oline coach that had been their since before belichick retired a couple years back and they just fired his replacement. If they can't fix that the end of the evil empire may be in sight and I'm hoping it happens with brady still here. Cheaters were not good this year and benifited from a very friendly schedule as did we.
Think on this too. the cheatahs won their first 3 suberbowls with a totally different style of play. defense won those games and even last years. all the years when they scored 50 points every week produced no superbowl wins.
the first 3 superbowls they were caught taping and clearly that played a part in their winning. Their 4th win, again they were caught cheating, maybe the deflated balls didn't play as big a role as the videotaping but still. Caught cheating. I, for one don't believe the ever stopped with the video thing. the league only destroyed 2 of their tapes and they had many many more then that. Why would they quit? But I digress.
I have always loved watching Peyton play. He was never surrounded with the players that brady was and still won a ton of games. Many including myself , knocked him for not winning in the playoffs but I apologize. He has now beaten brady in 3 straight AFC championship games. The past 2 years he may not be the same but give him credit for adapting to a system totally against what he has always done. Many would have had a hard time with it.
to answer your question. I think there will always be a few qb's that step up above and beyond the pack so I don't think things change much. No matter how good you are, there is always someone better. And yes, lets hope our qb is one of those next elite ones.
in the mean time lets at least make bradys last few years miserable
