You still have to defend them if they aren't reported as being ineligible. If the Patriots got a touchdown because the refs didn't notice that he was ineligible but the Ravens did, they never would have lived it down. Not to mention the guy that went to line up with him would have had to look at everyone else in the formation to process the fact that Vereen was lining up in a spot that made him ineligible.
Yeah, they couldn't "not cover" Vereen on the outside. That sets up a mean WR screen with the receiver on the outside and Vereen 1x1 blocking the corner...not good.
Incidentally I'm coming around to the biggest flaw in this whole thing is Manatee reporting as I/E on the first play, then switching back to E on the next play when Vereen reported in as I/E. That's the entire crux of the argument right there. I'm just going off the media reports here that that's what happened, because the prior throw went to Amendola, but Vereen seemed to go out for a pass, supporting that he was E then I/E, while Manatee was I/E then E. You can't do that.
That seems like a flagrant violation of the rules as written. Let me put it differently: if that IS legal, that's absolutely absurd, given that Vereen reported in as he was walking to the line...so the Ravens, within 4 seconds, have to say "OK, last play that guy was I/E, but now this other guy is I/E, so that means that if he's I/E than that guy is E...but where is he? Oh, he's on the line, over there."
No chance. The rule says that a player wearing an E number cannot report as I/E then switch his status on the next play without something happening (timeout, etc). The rule makes sense for this reason, the Patriots had a smart idea but got sloppy with the execution, the officials screwed it up then and WORSE the NFL continues to screw it up now.
I will desist if I see one person address this issue without a freeze-frame of a the controversial formation, which isn't the issue at all.
