A few base plays that work from multiple formations. I formation, toss sweep, iso, power, counter, sprint draw, inside zone, outside zone, FB roll, FB trap, Belly, options off of trap and belly... Spread series, zone, read, QB iso, counter, QB counter... Keep it simple, multiple sets, motion, but plays that work and kids can execute to perfection vs any front! Wait a second, that sound like the OZ-BONE!
Only problem with Callahans system is college players dont have 15 years of eligibility and have to attend classes...
