There's a couple of things that need to be stated.
First, this EXACT crew (I know all these guys) worked a first round game 2 years ago where they flagged and enforced a hideout play, taking away a TD. I'm not sure, but I believe they told the coach not to run it but he did anyway, then threw a fit after they flagged it. I saw the game on tape and the play in question.
Second, they missed, per 2-27, an illegal formation (I'm not sure how many are really familiar with that rule) IF you consider that rule infraction a gained unfair advantage. While I will concede its debatable in this play, its still an open question as to whether Team A gained an advantage. This was basically a fly/go route with single coverage and the DB had his eyes on the receiver who's shoulders WERE parallel to the LOS. Yes, you can argue other defensive players could have helped out but the way the play was run, I don't think anyone else would have been much help. Illegal formation is a 5 yard penalty and subject to advantage/disadvantage (just like holding and BIB -- nothing specific in rules about "point of attack" yet we all enforce it that way).
Third, not everyone is aware of the bulletins. I wasn't aware of the one on this type of play until reading it on here -- in fact, I didn't even know it was a bulletin for a few posts. Yes, we all should be more aware of them and TASO should make them more known, but as of now, they aren't -- and if there's additional play applications such as this one (nothing specific about hideout plays except for equipment OR substitution, and this involves neither) we need to be informed if we are expected to enforce it.
Not trying to be a homer for these guys. Just bringing up some additional thoughts on here that should be considered.
