Unique thing about Mahommes, Watson, Rodgers, and Wilson is:

Even if the DC makes the perfect play call; and the defense gets lined up correctly; and, the unit executes to perfection...these four QB's have the mobility/presence of mind to turn bad situations for them into (at the very least) plays where there is minimal loss. And in the case of Mahommes, Wilson, and Watson, many times they can pull significant gaines out of their arses.

That type of stuff simply can't be coached.
