You're gonna have to go into more detail than that.
Setting up a playbook of literally every Flexbone formation, Maryland I, Wing T, Wishbone, throw in I Form Tight, and Strong/Weak.
Run, run, and run. With Flex, you have a slotback and wingback on each side of the line like a TE, so you can mix in RB streaks and use their speed vs a man on man LB matchup and burn them deep when they start blitzing and playing the run hard.
The instant replays are never right. One time I reviewed a catch where the WR caught it with both feet out of bounds and it was clear as day on the replay, and they still ruled it a completed pass. Happens every time, they always get the replays wrong.
