Legacy, I agree with you but the signal between wings is our own and, to my knowledge, has never been seen by a coach. Our signal is not a normal football signal. It's just a quick point to the team that fouled and it is quickly given by each. If they point to the same team that fouled, the LJ will head towards the R and give the signal. If they signal opposite teams, they continue in to determine who fouled. Each can easily see the others point and it has been, so far, quick and easy. Even if a coach figures out what we are doing we will explain what we did and how we determined who fouled. Not much different than any other foul we have to explain.
