here are a few ways to make some new formations out of the Run N' Gun playbook.
making the near and far formations(you can also have hybrid near and far formations) - come out of either strong I, or weak I(either formation strong normal or strong TE, or weak close or weak twin WR)
Setup - if your thinking of running the ball, you have to audible to a quick pass play. motion the HB up, and reset really fast(when he gets to the FB reset it. it may take time to get down, but it works) if your looking to pass do the same thing.
making Jumbo T - come out of strong I twin TE. if your running, audible to a quick pass, and motion the HB up and reset really fast. if done right, then he should be right beside the FB(or close to him, maybe a foot or 2 behind him but thats fine) then motion the INSIDE TE to the left(he comes down next to the HB and it lookd like Jumbo T.
making full house wide - come out of Strong I twin TE and motion the inside TE to the left.
