At the BC-Calgary game there were a couple of offside penalties charged against BC that I didn't understand.
On one, the BC defensive lineman entered the neutral zone (he moved his hand forward ~12 in) and then jumped back to give a yard before the ball was snapped. My understanding was this should not be a penalty yet the ref blew the play dead and automatically assessed 5 yards against BC. (If the player crossed the line of scrimmage, contacted a Calgary player, or made a Calgary player move, then as I understand this should be a penalty.) I was at the game so I didn't get to see a replay - did I miss something or did the ref just screw up?
The second one was again against BC, but this time on offense. This time, a Calgary defender jumped into the neutral zone and caused a BC O-lineman to release from his stance. My understanding is this is offside on the defense because the O-Lineman moved after the defender had entered the neutral zone. In the game, the penalty was assessed against BC. Again, did I miss something that appeared in replay on the tube or was this another ref screw up?
