First off, if there was zero data to support this being a player safety issue, why even put the rule in front of the committee for a vote in the first place? Troy Calhoun supports the rule...it's brought to his attention that player safety has nothing to do with it and there's not one shred of evidence to even suggest otherwise....now he can't support it.
And to JR's point about Lord Saybinz' minions coming up with every rationalization to support it...where were these arguments before LS whined about it? It wasn't an issue for anybody until the exalted one complained. Even had one Bama fan call our local show and say it has to be slowed down because every play is supposed to be reviewed. HUNH teams are trying to cheat by running a play before the last one can be reviewed.
