Watching lots of non Bills games over the last week I have to conclude that zone defense especially in the 4th quarter in a close game is one of the stupidest strategies in football. I saw many completions last week (even in the SF game ) that the defenses simply let receivers just run past them and into the next area to be wide open for an easy catch while they were distracted by another receiver. If the QB has time to throw, this approach is insanity. But this is the approach that our defensive guru HC sticks to in most of these situations except maybe on the deep patterns. And on those patterns our DB's are often way off the ball, late to get there and either cannot break up the play or get a DPI penalty because they are not looking at the ball. I'd love to believe that McD learns from his mistakes but this season has repeatedly shown us otherwise. Kelce needs to be jammed at the line and smothered in coverage because Mahomes always has time to throw.
