Based on his reaction, Wilson wasn’t happy. Brady surely wouldn’t have been happy if Wilson had exercised his prerogative to blow Brady up.
And Wilson could have done it. If a quarterback decides to stick his nose into the fray after a turnover, he becomes fair game to be hit aggressively.
The fact that defensive players are wired to not hit the quarterback gives them broad freedom to do things like drop a shoulder or, as we’ve seen in the past, feign going out of bounds when running the ball and then taking a few extra yards after the defender pulls up.
That’s why people like Steelers defensive coordinator Keith Butler will say that, when the quarterback becomes a running back, he’ll get treated like a running back. It’s a license to treat the quarterback like something other than a quarterback when the quarterback becomes a runner.
Even then, plenty of defenders remain hesitant, given the perception/reality that certain players (like Brady) get extra protection. Indeed, what would have happened if Wilson or some other defender had flattened Brady? Would a flag have been thrown? Would Brady have complained to the officials if a flag wasn’t thrown?
At some point, some defensive player will treat a quarterback who became a runner or a potential tackler accordingly. When it happens, the quarterback will have no basis to object.
