Berrios is not good enough to beat 1 on 1 from the Split End position against teams with competent CBs. I watched him over and over try to separate and just get carried into his route. He is weirdly out of position. It worked in practice, but this isn't practice where the QB wears a special shirt and the OL provides a nearly perfect pocket throughout. That extra tick is the difference between Berrios catching slants and ins and...not.
