Not sure if this warranted ANOTHER thread. But yes there is something off. On in hit he was on camera for a brief second grabbing at an ankle. I still worry about that face mask he took in Dallas and any reoccurring damage to his neck.
But you also have to factor in that the OL protection has resorted to him making decisions in 1.5 seconds and there is no way he can plant his feet and make the reads. Where as earlier he had way more time to make progressions and set up for a good pass.
