The coach was me, and I still contend that getting my players out of there is my job, not yours. You aren't equipped for it, are charged not to touch players and have the added duty of getting the numbers of the participants and those leaving the bench. We don't have those restrictions or duties. Our sole purpose at that point is to get our kids out of there and keep them from doing something stupid.
I am not advocating that the entire staff take off. We have assignments. Most coaches are to get a few yards in front of the bench and face the team, making sure the players on the sideline stay there. Two coaches are assigned to get out there and get our kids out of a fight.
Thankfully, we have never had to use our plan. But if the situation ever arises, rest assured, two of our coaches will be there to get our kids out of the fight, while the others keep the rest of the team on the bench.
