The Denver Broncos offense used to be pretty straight forward from 2014-16. Demaryius Thomas and Emmanuel Sanders would account for half the passing offense, while a tight end would be a much less-utilized third target. The running backs would follow Thomas and Sanders as the third and fourth most productive members of the offense.
And that was simple enough for opposing defenses to strategize against. Cover Thomas and Sanders, defend the running back, be aware of the tight end, and the fifth skill player really wouldn’t be too much of a threat for anything.
