If there is one ‘benefit’, should you so choose to put it that way, to having a quarterback other than Ben Roethlisberger under center, it is that it pretty much guarantees that it will produce a higher percentage of snaps from, you know, actually under center, rather than almost exclusively out of the shotgun. And, generally correspondingly, it will produce a higher percentage of passes off of play action.
For the past several years, going back to 2012, nobody in the NFL with a decent number of snaps has thrown passes off of play action less frequently than has Roethlisberger.
