Do teams not use the same 11 players on field goal blocks for every play?
I can understand how you get 12 players on defense because someone was confused about what package you’re running, but if you’re the 12th guy on special teams shouldn’t you stop and think “Hey, I’m not usually out here for these plays, maybe I’m an extra?”
Ah, ok found someone else explaining it and I screwed it up.
Pierce saw he only had 10 on defense (playing a man down) so he ran up and got the infraction (giving 5 to get his man on the field).
The only reason I could see for doing it with 12 on the field would be to just not risk a free play (because you’re right it’s 5 either way).
