Is it possible that Pfaff is overthrowing his receivers on the deep routes, when compared to his success last year, is that this year's receivers just aren't that fast? On a positive note, I liked his pass to Lenahan in the flat where Lenahan had plenty of room to do his thing.
Many of the receivers are his classmates that he has played with for 4 years. He should be familiar with them.
Pfaff has been overthrowing his receivers on sideline patterns too. They were really off on such passes in the Springfield game and there has been some slight improvement, but he missed open receivers on such routes against Hoban.
He was also missing the pass in the flat during the McKinely scrimmage, Springfield and Mentor games until he finally connected late in the 4th quarter vs Mentor with passes to Lenehan and Martin. Since then, he's had a better touch on passes in the flat.
