Scouting Report: Let’s start with fun to watch because he makes a lot of plays and rarely is flat or at a loss to find something. He follows in the tradition of good deep throwers for Yurcich as he can throw the deep ball down the middle or on the sidelines well. He rarely misses on intermediate or deep throws short. If he misses, he is going to be long which allows receivers to know they are going to extend to or chase down the ball. On the out route he is often high, same with middle short to intermediate. His long throws are more ropes than floaters, in other words look more like Taylor Cornelius that Mason Rudolph. His release is quick, which allows him to release the ball in a slot between ¾ and over the top. The ball does drop a little low, but he brings it so quick it never mattered. He will sometimes drop between ¾ and side when throwing on the run. He has more short throws when throwing on the run, but that is the same with most quarterbacks. Once he scrambles, it is 80 percent he is going to end up running and he has good instincts. He doesn’t run away from people but avoids them and has good moves. I saw him hurdle twice and that is impressive. You can tell by the way he plays that he has some “it’. His height did not ever bother him in the three games I watched, and I watched the playoff loss where they were pounded good by St. John Bosco. He got frustrated but who wouldn’t. He was running for his skin the whole game.
