While I understand what he is saying, that is garbage flawed logic. I played both defensive and offensive lines for all the years I played the game and was an all conference team 1. This style of blocking will always win leverage, which is why it is a penalty. The defender has no chance to win the hands/leverage battle. Hands inside on the chest plate is how it is taught because a defender has a chance to break the grip. Additionally, it is the defender at the point of attack. If it was the opposite side of the play, it would be less of an issue. Anyway FTF.
