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.
They played a good game, hang in there, they may take it next year, they are young and they are talented.
That being said........Go Pistons!
