After re-watching in slow motion a few times, here's the sequence as I see it. The overlaid scoreboard is in the way of the Texans sideline, so all players and coaches are not visible: -Jacoby Jones is busy counting Texans players making sure we have the right number on the field...apparently he is not looking into the Jags backfield. -unidentified Texans player scrambling to get off the field before the snap. Must be why JJ was counting. -Antwaun Molden runs back and forth trying to find his spot, which is on the other side where there is only one Texan ready to bump the Jags ST player. -referee almost backs into and blocks Molden. ***** zebra. -unidentified Texans coaches, at least two, seem to become animated judging by their walk. maybe they saw something on the field...can't tell due to CBS scoreboard display. -Fred Bennett can be seen looking into the Jags backfield, yet still does not change his position. -Dominique Barber gets turned around and is not able to get a clean tackle attempt on runner. -Del Rio raises his arms in triumph on the sidelines. -Jacoby Jones makes fairly pathetic tackle attempt. -Faggins and Bennett become aware of the fake...Faggins tries to strip the ball and misses the tackle. -Jacques Reeves and Dreesen arrive just in time to congratulate the Hag on a great fake. My take: there was some confusion on assignments to begin with on this play. Yes, of course someone should have called TO, but maybe like Kubiak said, they saw it and thought they could stop it. I tend to agre with him...they should have been able to stop a 4 yd run. However, the Jags did a great job on the blocking up front, catching the Texans line off balance.
