are you predominantly in gun or under center? im goin over the PB right now and some runs that jump out at me that have potential are:
weak flex twins: toss weak, stretch, and HB gut.
strong tight pair: strong toss, power O, lead dive, and counter.
singleback bunch TE: toss crack, and HB sprint.
singleback bunch: quick pitch, HB slash, HB draw, and counter weak.
singleback ace pair twins: counter weak, HB pitch, power O, and HB stretch.
singleback ace pair: power O, counter weak, inside zone, and HB stretch.
singleback jumbo: HB stretch, inside zone, counter weak, and HB dive.
I-form tight pair: power O, counter weak, iso, HB sweep, FB dive, and FB fake HB toss.
I-form tight: power O, FB dive, HB toss, iso, and HB blast.
I-form close twins: HB iso, HB counter weak, stretch, FB dive fake HB, and FB fake HB toss.
if you build little mini schemes around these plays and runs i feel like your running game could sky rocket, its all about mixing it up though dont just go to a certain formation and call the same run play cuz its effective it'll be more effective if you mix the runs in that formation up so your OPP. cant key on a certain run, thats why in a mini scheme i like to have something that goes up the A gaps, some kind of counter and a toss if possible, mix that concept in with some nice pass plays and PA and your set man.
