My point is that you specifically mentioned that the WCO requires "unselfish" receivers and QBs that can make their progressions (not just throw the ball to the same guy every down). Is there some other offensive system that thrives with a selfish receiver that you throw the ball to over and over?
No, but there are some WR's who believe that would be an excellent system.
Because I can't think of any, and I certainly don't think the Bears or Shanahan's Broncos fit that bill.
If I'm not mistaken Shanahan traded Marshall and the Bears have yet to find out what Marshall thinks.
I mean, if you look at a passing philosophy that's basically the opposite of the WCO, the Gillman/Coryell downfield-attack offense (like what the Greatest Show on Turf-era Rams ran), they still rely on unselfish receivers and progression reads.
Not the extent that the WCO does.
