Brown would have two. So would Gannon (and be in the HoF) and Janikowski (who will be in the HoF one day but looks set to retire this year)
Gruden wouldn't have left and they wouldn't lose to the Bucs the year after. Al would have his superbowl rings and stop throwing the farm at bad trades to get it. Which means BB doesn't get a bunch of extra picks to help form the Patriots dynasty.
He also may have taken his hands off the wheel sooner and let Gruden call the shots, no missing on Big Ben or Rodgers, and no drafting Russel over Megatron.
Bill also could have gotten rid of Brady for that costly error, he's iced people for less. Brady goes to Dallas, suddenly Romo needs a home.
Or maybe he stays, but the Patriots don't attract the players they did without that first ring, maybe they win a championship or two, but they don't get 5.
Manning does though, without the Patriots dynasty, he turns the Colts from being underachievers into an Empire, even if he still gets injured, the success in a non Patriots dominated era means they retain him. And so Andrew Luck becomes the starting quarterback for the Browns, who avoid wasting two first round picks on Trent Richardson and Brandon Wheedon and actually begin to build a decent team five years earlier.
This may mean Denver doesn't trade out of the first round and take Wheedon instead, which means the Patriots don't get to trade up for Hightower and Doug Martin becomes a Giant.
2013 matters little because that draft SUCKED. But the Browns with Andrew Luck, can get themselves out of the quarterback chase. Come 2014, the Raiders likely don't take Mack or Carr (both of whom could end up Broncos if the last few years were run by Wheedon, and a Mack/Miller offence scares me) Manziel may end up a Viking (who's front office may give him a better chance to not be a screw up)
Or, the Raiders lose to the Steelers defence the week after, BB realises Tom made a rookie error and nothing changes, ever.
