This is what I saw also. The Dolphins had a stutter go called which is real nice against a blitz if you get the time and have a gutty QB. The corner bit the cheese and got roasted (I'm sort of mixing my metaphors there). Moore did a good job hanging in because there was almost a free rusher coming at him and he got clobbered. I'm not sure I'd call that a blown coverage in the sense someone covered the wrong person or anything. Similar to the Hartline touchdown, which was a deep post and go called against three deep zone. Another nice call against that coverage. The corner bit on the post, Henne saw it and Hartline ran a real nice route. Boom. Wide open.
My only problem with that play is it highlighted a problem I see come up again and again with Hartline when I study the tape: the guy falls down a lot for no reason. As soon as he gets the ball in his hands and he starts running he trips over his own feet and stumbles to the ground. Happens over and over again. There was literally no reason for him to stumble and fall into the end zone on that play. None. It was a perfectly thrown ball he caught at his waist. If we had been five yards farther away he wouldn't have scored. If we had been twenty yards away -- God almighty. Imagine he catches that ball with an easy touchdown in front of him and he just falls down (this happened last year on a flea flicker against Tennessee IIRC). Hartline's inability to keep his balance with the ball in his hands is extremely frustrating. I mean, what good is a "deep threat" who does this?
