Quick question: I've tried to look it up but I'm not getting a lot of clarity. Smith grabbed McCourty's facemask (on his TD) at the 9 and dragged him the rest of the way. The refs let the play go. But what if they had called the penalty? Personal foul, offensive facemask. I know it's a 15-yard penalty, but where would that have been enforced from? It was 3rd and 4 from the Pats' 29. The penalty occurred at the 9-yard line, meaning they picked up 20. If it's enforced from the LOS, it would have been 3rd and 19 from the Pats' 44. If it's enforced from the spot of the foul, it would have brought it back to the Pats' 24. Would it have been a first down then? (because the new LOS would have been past where the Ravens needed to get for a first down) What is the rule on this? Thanks!
