Today the NFL revealed the rule changes that will be implemented for the upcoming season. There’s nothing too drastic on this list:
The one change that sticks out is the total ban on chop blocks, which occur when a defender is blocked low while already engaged with another blocker up high. The tactic was already illegal in passing situations, but was still allowed on certain running plays, particularly ones involving a zone blocking scheme. It wasn’t uncommon to see a defensive end or tackle get chop-blocked while trying to pursue a zone run from the weak side.
