I would have to think Norman was told to tighten up his coverage on Marshall against the Bears, he was just scared of getting beat over the top. He was later benched in favor of a more physical CB.
However, the coaches should have given him some help so he could press without worry.
I'm not sure I agree with this.
Rivera even said himself: "Our thought there, was to make them beat us systematically"
Remember that famous quote?
