Chop Blocks

[mike rumer]

I am a umpire.LOVE the middle.As for chop blocking the umpire must know, on dive plays all blocks WILL be low.
On pass plays is when chop blocks occurs the most.The offensive lineman will back up blocking high.If another offensive player makes contact low,[below the waist], you have chop blocking.In all the games I have ever done,it`s usually [not always] the team that getting thump badly doing the chop blocking...Sometimes another offensive lineman may get knocked around and ends up hitting the defensive lineman low,NO foul..A GOOD umpire will know the deference.
