Tonight I was at my Texas State Bobcat vs. Cal Poly game. Team A, 2 and goal from the team B 1. QB hand off to RB who is pulled down by his facemask at the team B 8 for loss of 7 yds. My question is where is the enforcement spot. The crew assessed 1/2 the distance from the end of the run at the team B 8. Team A 1st and goal from the team B 4. I thought this was a basic spot penalty to be assessed using the 3 and 1 rule. That would make it team A 1st and goal from the team B 1/2.
