Defending a mobile quarterback at the college level is a defensive nightmare. That’s why the best are virtually impossible to stop; mobility has canonized names like Vince Young, Tim Tebow, Johnny Manziel and now, Lamar Jackson.
The mobile quarterback is such a difficult assignment to guard because you can’t gameplan for him. He’s one cut, missed read or broken tackle away from racing down the field and his ability to keep plays alive and push the ball vertically is indefensible because there’s no coverage for that.
Of the four great mobile quarterbacks mentioned, Jackson has had the least amount talent around him — translating into more losses and an easier formula to (theoretically) defeat him.
