Here, the Saints are running a Tampa 2 look. Safety Marcus Williams and cornerback Marshon Lattimore have cover 2 responsibilities, splitting the field. As you can see, linebacker Manti Te’o falls back into a deep zone under the safeties and picks up Vikings receiver Adam Thielen, who is running a post route. At the top of the screen, Lattimore blows this coverage as he fails to maintain his half of the field. Rather, he drops down on Vikings tight end Kyle Rudolph. Had Lattimore been in his zone, he would have been in an excellent position to break on the ball and make a play.
