Once a narrative sticks to a quarterback, there's not much he can do to fix it.
In the social media age, Tony Romo was the first QB who was stuck with the steady drumbeat of negativity, no matter how well he played. A dropped field-goal snap in a playoff game, a couple more postseason disappointments and poof, it was set. Romo wasn't a winner, whatever that means.
Romo retired and handed the baton to Kirk Cousins.
Cousins has been a good quarterback for the Minnesota Vikings. That sentence alone caused plenty of eye rolls and chuckles, but it's true.
