Watched it again last night thinking like you and @Shaw66, but Josh was DEFINITELY down at the two. Not even arguable, and the refs spotted it appropriately. Watch it again from the reverse angle.
I thought the non-calls on Shakir and especially Cooper were right. The slight hook on Shakir didn’t impede him (the pass was off anyways) and that literally happens on almost every play. The defenders are actually allowed to contact receivers (after all, it’s a contact sport). Outside of the Dawkins call (compensated for by the very questionable call on Tre White), it was a pretty well officiated game.
