Chop Blocks

[FridayKnights]

Like to get some information on chop (cut) blocks by the o-line.

At a HSFB game last year I asked a ref if chop blocks are legal. My definition of a chop block is when one offensive lineman is engaged with a defensive player and another offensive player engages the same defensive player with a low block. This is illegal in the NFL as it has a high injury risk factor.

What the ref told me is the block is legal as long as the second defensive player waits one second after the first player engages the defender. If the second player hits the defender in less then one second its illegal. The ref said as long as the offensive player waits the one second it does not matter if you hit the defender high or low it's still a legal block.

Most people argued that hitting a defender high and low (high/low block) in the neutral area (tackle box) is always illegal.

I know the chop block is illegal in the NFL does anyone know the rule in HSFB?
