I have seen that happen before in only a few games, don't think it happened here. I think the Hawks were the better team but just did not finish. They really didn't. They lost the game themselves by poor plays....two missed FG's, and the missed touchdown by the receiver at the end of the first half.
Bad timing by the Hawks themselves, not bad referees.
I agree that the Hawks missed some plays; Stevens had some drops, but there was also one clear hold against him that wasn't called. But the killer calls were the DJ push-off (ticky-tack) and the tick-tack hold on the Stevens catch at the 2. It was a close enough game that the Hawks couldn't recover from those two.
Were you actually watching the game?
