None because it doesn't really work in the RZ. It didn't work for either.
In the Chiefs example, the Colts DE blew his edge contain. In the Cowboys play, the DE didn't hold C-gap leverage and the unblocked LB went to the wrong gap because of it (might be other way around, hard to know without assignments). In either play, it doesn't work if the defense maintains any discipline.
Without a play fake to get a false step from LBs, this play is useless more than once or twice a season. With the play fake, it's basically a standard jet sweep.
