run the HBDS a few times to get'em scared of it then hit them with the HB power out of the same formation, cuz most times guys will overload the side you've been running the HBDS to leaving the opposite side open, mix the slot, flanker, and HB screen in with this and bam you got yourself a lil mini shceme, gun split slot HB power O is another great run out of gun cuz of the FB blocking for you just motion your slot reciever until he gets just inside the tackle then hike it then its just reads from there. Gun trips open HB off tackle is another great run out of gun cuz of all the receivers that you have on the play side of the formation, look to bust it out wide using the WR's as blockers, gun trips TE HB off tackle uses the same concept. im not too familiar with the undercenter plays but the toss out of the strong tight pair formation is a real nice run to utilize.
