Last time at the Yale Bowl, their team was very effective at cut blocking. For a while. there was a Lehigh player lying on the ground with the medical staff after almost every play. I think 4 or 5 LU players were carried off the field and knocked out of the game with season ending injuries to the knees or ankles. This sapped momentum and removed some of our best linemen.
I do not believe the refs called a penalty once so maybe this was a legal form of cut blocking? In any case, it got the job done and Yale turned the game around and won against a depleted Lehigh team.
