it confirms what I said. The linemen is diving at Martini's legs. It looks like he may have got tangled up as he's attempting to dive to where he only gets a piece of him - then he basically lands on Schmidt. When I said "missed" a block, I didn't remember if he hit the other Irish player or not. I just remembered that it wasn't a clean dive and block.
Obviously other teams have their linemen throw blocks in similar fashion, but not at the level of Navy.
On your number 2, I appreciate the snarky comment, but Cut blocking is an offensive linemen trying to take out a defensive player by hitting their knees or lower. That's exactly what he's attempting to do in the play.
