For serious, why would anyone "defend" his play? Their job is to practice plays and get better at them. If asked this question by a reporter, their job is to be a good teammate, however they want to interpret that.
My first guess is that every guy in the locker room knows they have things to improve on, and my hope is that they are too singularly focused on that to volunteer "defenses" to placate fans who are in search of a new problem to B word about.
