In the run-oriented offense there's a "counter play" in which the offensive line primarily blocks one way, and the back takes a step that way in order to get the defense to overcommit.
Then, the RB will cut back and go to the other side where a couple of players are "sealing off" the end of the line.
When it works, its a thing of beauty. In this particular case, it didn't work, and Ricky went for a gain of 2 if memory serves.
But it was nice to see some thought given to play design, even if the execution was sloppy. Since the Phins will meet the Jags in the regular season, they didn't want to give too much away, but this just goes to show you that they have lots of things up their sleeves for the season.
Heck, I can't remember the last time I saw Miami run a counter play - at all.
(Hartline came to the right, Thomas pulled from the RG position to the outside as he might on a sweep, the C, RT, and LG blocked left; Long blocked right, as did the FB.)
