Diggs and Carson both playing far off and Diggs had to go around Carson to get to his man. I'll never understand why in that situation if you're playing man coverage you don't play press. If they beat you long I can deal with that. If the WR makes runs a great route and beats you I can deal with that too. At least in those situations you give your pass rush an extra half second to a second to get home. To give up with simple underneath throw on 3rd down is just unacceptable, and if Diggs gets his man covered, Carsons man is also wide open for an easy completion.
You can almost see it in Jackson right after he motions the receiver. He resets, looks back over at the bunch side, almost like he is in disbelief that the Cowboys are giving him this easy throw.
We will have to wait on the all 22 tape to come out but im also curious where the the 11th man on the field was, because for some reason he was so deep that he wasn't even in the shot on the broadcast.
