First, it wasn't triple covered. He was trying to fit in between the CB who is sitting a bit and the safety playing cover 2 shell. It was 2 guys and it's a sandwich throw. Pickens wasn't out there. Why? Because Schotty likes personnel groupings around certain plays. They run a lot of Turpin, Flournoy, and 2 TEs or that grouping plus Lamb. Look, you don't like the throw, fine, but WTF do you want him to do. Check down and get 5 yards and kick the FG, folks would complain. Give a guy a chance to make a play and it happens to be a gadget guy. Again, do you think Dak looked at the roster and says.... I want that midget who has no vertical threat to be my outside option? Again, this a fundamental issue..... Unless someone was injured, Turpin shouldn't be that option. FG was 95% plus going to be the 4th down option AFTER they had scored but taken off the board the play before because of penalty.
So....... maybe the coaching staff? Perhaps.
