If 2 players contest the ball ie the plow and mckay incidents, it's becoming pretty clear your only option is to lay down after contact until you ensure the other guy is OK. If there's a chance he's concussed, stay the * down and pretend you are too. Keep your weeks off to 1 for concussion protocol as it's going to be worse if you get up.
