I agree with how you're looking at this, but its not reality. This is similar to how the strike zone is in baseball. Every ump calls it just a little differently. Having said all that, i could've sworn that refs were supposed to give these guys/coaches warnings before they threw the flag & i don't recall that happening in the Vikes game for us. Maybe it did happen it just wasn't announced and made known...but still. these 1st few games it just seems like the refs are arbitrarily calling it. Like guys play a whole 1-2 qtrs in the same game where noone gets a flag for it, players think everything is all good..... and then all of a sudden in the 3-4th you get 2-3 flags for it....& its usually against 1 of the teams where they start calling it like that. Once that happens and kills a drive or 2, the other team sees how they're starting to flag for it and they adjust accordingly & the flags go away for the rest of the game. Its been very inconsistent so far in how & when they're choosing to call it.
