all offensive systems benefit from timely accurate passes. that you choose to focus on wco as unique in this regard suggests you think there is a singular trait or feature of these different systems that differentiates...and that only a particular kind of QB could succeed therein. while there are definable differences (concepts v trees, etc) what mainly separates the various nfl offenses today are 1 terminologies and 2 particular skillsets of your offensive personnel. that's why shanahan's wco w purdy looks very different from andy reid's w mahomes, or even from his original offense in atlanta w matt ryan and julio jones. look at what mcvay is doing right now w stafford- looks very different from the offense he ran w goff, yes? much less under center, allows the QB to dissect, doesn't rely so heavily on play action...your personnel informs your scheme
