I believe the strategy they used had two goals, not one. The first one was obvious which was to put Patmon in a position to potentially block the punt. The other was to have Scandrick in a position to defend the fake punt/pass play. Now the latter has been mentioned, but the hidden goal with that second part was to bait the kicking team into trying a fake punt/pass. If Scandrick was already lined up helping Patmon double-cover the gunner, the kicking team would not have tried to fake punt/pass the ball which would have eliminated the second goal. The other downside to this is that to trick the team into doing it, Scandrick would have to time it perfectly before breaking toward the gunner after the snap or else he would have tipped their hand. He was a little slow to react which is why he was late reaching the gunner/receiver.
Now, that said, I would have done exactly what they did, but have Scandrick immediately take off right at the snap so the kicker would see Scandrick running to cover the receiver. The best case scenario in that situation would be a punter who hesitates, thinking before the snap he was going to fake punt/pass the ball, but realizing right at the snap that the pass receiver was no longer going to be wide open so he would need to kick it instead. That slight hesitation might be enough for Patmon or Carter to get in and block the kick. The next best scenario with that tactic would be a defended pass because Scandrick would have been right on the receiver by the time the ball got there. However, the downside would be if Scandrick drew a pass interference penalty, which would be quite possible given the distance Scandrick would be covering at a full sprint to reach the receiver.
Personally, I don't think this team's offense needs to take risks like that unless its late in the game and they are behind by more than 8 points. I'm glad it worked out, but I'd write that off as going 1 for 1 and calling it a season on any more attempts.
