I am curious as to what triple option you are referring to. If you are talking about the Marathon Veer, find Vance Jones and get some old tape, he has it somewhere. When he was at Sanderson, he ran a good deal of it. Later, not so much.
If you are talking about O'Brien Veer, which is described in "The BOOK", by C.H. Underwood, contact C.H. or Benny Grill, who is probably around Benjamin. If you could find the All Star game of 78 maybe, that Benny coached and had two guys who had run the Veer in high school, and made a great athlete into a QB, man under, that would be a great film, but unless Benny has it, do not know.
The fore mentioned guys, not sure what venue they played under or what they run, but just mentioning two true triple option from back in the day.
