Maybe, and Rodriguez took it from the triple option offense and modified it in terms of how the zone read works.
Honestly what Allen did is not a pure RPO offense. The triple option was created in the 60's in Houston by Bill Yeoman. And I know that he had schemed the pass out of the option, when the QB decided to keep, the receivers on the QB option side would go into scramble rules, so the QB could keep or throw the break.
I used to have his playbook, because at one point I wanted to see if I could install the Triple Option at the Bantam level, but it was next to impossible.
The main problem with the pass element of the triple option was that for the most part the Oline plays the run and goes down field, which was illegal at the time, so you had to modify your line responsible to what would be an aggressive zone pass block.
What Flutie and Allan are describing is more of a ride and decide option package with a receiver break. Its really a single play RPO.
Its not as effective as it used to be because Ends have become so much more diciplined in what they're doing.
Also what I've found is that nowadays most of these packages have gone away from reading the end and have gone to reading the outside linebacker on the run side.
