See CB hs merit you can learn something every day. Here's more knowledge for you. you can run a sweep with an olineman if you choose , it just won't work when the Defense is keying on that olineman as the ball carrier adn that o lineman starts 7 yards deep and there are multiple defenders outside of the box to the side the sweep is going too....
Actually even if you had mike vic, adn teh D was misalligned, running teh ball with an olineman is still ill advised.
