Trevor Penning is PFF’s top graded Saint; Penning is highest graded NFL OT in Week 10

Some of it was definitely coaching, but I think a good bit was just Penning working hard and turning the corner when it came to believing in himself. Even after working with Duke Manyweather in the offseason, Penning still struggled in preseason and I remember Manyweather posting how Trevor just seemed to not be trusting the technique that he was shown at all.
Not some , a lot of it was coaching not just Marrone but the decision to start hin last yr was bad after hardly any work in his 1st yr and the offseason
