This footage could partially explain why the Green Bay Packers vaunted defense played so poorly against the Arizona Cardinals last Sunday (although we think there are two other clear-cut reasons).

In it, you’ll see Packers defensive coordinator Dom Capers, who appears to dose off and then suddenly jerk back to life like someone who’s trying to watch a late-night movie well past their bedtime.

Maybe Capers is narcoleptic or maybe he just needs some coffee, but hell, I had been partying for three days straight and was running on three hours of sleep and zero caffeine during the Packers/Cardinals game and I couldn’t take my eyes off it. You’d think a member of the Packers coaching staff wouldn’t have much trouble maintaining concentration.

Makes you wonder.
