I'm not sure if we're disagreeing. I think the three plays - minimum - fulfills both the need to examine the player and also avoids the temptation for a free TO. As above, the sole hole I see is that the coach sends in a dispensable third stringer to stop play. Stopping that, if it occurs, would lead to a complicated procedure and judgment calls...You're right. However, there are now fewer kids joining Pee Wee and other clubs than in the past and a lot of that is due to injury concerns. Considering both solutions try to achieve the same result of reducing the number of fictional injuries impacting game play, there's no harm in putting a positive spin on it. There may not be direct liability for injuries, but basing decisions framed within the parameters of player safety as opposed to just the outcome of the game would put the schools, conferences, etc in a positive light.
