Cincinnati Bengals assistant quarterbacks coach Fredi Knighten keeps the same routine every Monday morning. First, he'll drop off his dog, a German shepherd named Vera, at day care. Then he'll arrive at the team's headquarters at Paycor Stadium around 6:30 a.m. and start accumulating game tape for the upcoming week. He'll look at the opposing team's cornerbacks and study the intricacies of their craft -- which hand they use to jam receivers, how they play releases off the line of scrimmage.
