Couple points: the only RB proven to thrive in outsize zone runs is Brieda with the Niners. None of the other guys have from what I’ve seen the speed to get to the edge. Also, the idea that ‘outside zone’ is an offensive philosophy, as opposed to a type of play and oline technique within a zone specific blocking scheme, is misplaced.
Further, not sure what outside zone runs (or inside zone runs for that matter) have to do with ‘streamlining’ the pass game, other than traditionally zone schemes utilize more athletic linemen who often are better pass blockers?
