Over the past several seasons, we have been developing the following philosophy regarding blocks below the waist:

As long as the block below the waist occurs on the initial charge immediately after the snap it should be considered legal, even in a scrimmage kick formation. We have been discussing this with the coaches in our pre-game meetings and everyone in the league accepts it.

If the blockers retreat or hesitate (while maintaining separation from the defenders) and the quarterback is dropping back to pass, this would create a situation where an illegal block could occur.
