There are times you tip your cap to the opposition but there are also times where you made the mistake. Throwing into triple coverage isn't the defense outplaying you, that's you making a poor decision. And, the pick 6, even if receivers were in the wrong area, you don't HAVE to throw the ball, especially when things have not gone according to plan.
It is Stafford's responsibility to manage those situations. He is expected to make plays but he is responsible for not making things worse.
