I don't see RPO in that light at all.
RPO is about box counts, and forcing defenders to commit. I'm not sure what an individual's ability to take over a game has to do with it. RPO is about hat on hat blocking/covering, and getting a numerical advantage. You aren't, necessarily, looking for a "home run". You are looking to move the chains consistently.
If that is not your preferred cup of tea, that's fine, but Gaskin (for example) is just fine for that role, IMO.
There are also ways to easily implement in game counter adjustments from RPO, depending on how the defense chooses to respond. It's a chess match that favors a read and react QB skillset, which is exactly what Tua is purported to be. It also gets our RBs away from between the tackles running.
There are many variations on RPO concepts, and many quality vids out there. This is a very good one, that deals with real world examples, both in the collegiate and NFL levels. It has been posted before, but I would encourage anyone interested in the Xs and Os of RPO to give it a watch.
