You guys are both wrong. AB didn't do anything wrong on that play. It was a case of the Chiefs running a defense that they did not expect to see in that situation, and both Ben & AB reacting appropriately. No one wearing black and gold expected the Chiefs to opt for that kind of zone defense including dropping Justin Houston in coverage.
It doesn't matter what they were expecting, you NEVER run behind the defender in coverage, NEVER. Regardless of whether we were expecting something or not, when you run up to a defender in coverage you ALWAYS cross his face so it makes it harder for him to jump the route. What they were expecting means jack ****. You are the one who is wrong, and you have the audacity to call out someone else for their support of a player when you won;t even criticize Brown when he does do something wrong. Hypocritical much?
