EIU did not record a sack on Saturday, the line was giving him plenty of time and he had a nice pocket throw out of. The mistake was looking down the receiver the entire time and not scanning the field. We see it happen all the time in football, a QB looking at his target the entire route and when he does, it draws the defenders to the ball.
Quick slants especially are designed to throw quick to the #1 receiver.
Sometimes the other team just makes a good play. Just like we did on Porter's 1st INT.
