This comes back to route running, Earl.
And we've already know that he's lacking in that department.
He needs to understand how to run that route against cover two with the CB playing underneath. He should have ran that route toward the inside so that he can use his body to shield away the safety.
Bray's throw should have been to the outside to begin with.
He can't let the safety have a play on the ball.
Still, Patterson has got to learn to understand the concept of the offense and how to adjust his route depending upon the defense he sees.
