At our final meeting of the year, one of the clips generated considerable discussion about a potential Roughing the Passer (RPS). This clip was from the Lemmonier Crew of 5 DVD under the Passing Game section, play 3. Below is the interpretation from Dr. Bruce Maurer:
I watched it a half dozen times.
If he knocks him to the ground I have Roughing the Passer since he could have avoided the contact.
If he does not knock him to the ground, then it is a "talk to:, then assess RPS if he does it again.
He does not deliver a hard blow with his forearm or shoulder.
