NFL Network broke down this formation on tape: http://www.nfl.com/videos?videoId=09000d5d80b01bc4 Of course our defense and coaching staff were horribly unprepared and slow to adjust to this play, but we need to give credit to the Dolphins for what the rest of the league will discover is a very creative and potent running attack. Their formation takes advantage of having two stud running backs in Brown and Williams, and uses deception and misdirection. This formation is as potent as the Colts' flex play, in that it is very hard for a defense to determine where the ball is going. If you don't follow Williams, Brown takes it off tackle. If you track Brown, Williams takes it for a huge gain. If Brown takes it on a sweep, he could throw it, and also Pennington is off on the side for some more trickery out of the formation. I don't see why this formation won't continue to give other teams fits in the future. The moment a defense starts to over-commit to one or both of the backs in order to stop the run, it leaves a huge hole on the other side of the field for a Pennington bomb.
