This is also the best view I have seen yet of Tua "looking the safety off" from the eventual receiver. You can really see Tua looking right, looking right, looking right, then suddenly throwing left. The safety never had a chance.
Actually, he is not supposed to read the QB's eyes there. He is supposed to play the WR. If he even remotely does his job, that pass is never thrown. There were other receivers underneath that were open, but that pass never happens.
