Because it was a pile up with 10 players. At the goal line. That was an idiotic play call in that situation with no timeouts remaining, that that's the exact reason why you simply can't call a run there with no timeouts. Also, there was ZERO sense of urgency by any singular player on the Ravens offense to get people cleared from the pile and/or lined up for the next play. Harbaugh deserved that one.I have no idea how that's not a penalty, they legit laid down and prevented the Ravens players form getting up. That's all kinds of BS.
Harbaugh LITERALLY told the refs to watch for that and they still didn't call anything.
