This, I think, is where you probably see Orr’s greatest effect on defenseman evolution…you can imagine there’s probably a similar curve on powerplay assists. To some degree, though, it appears that this revolution of the position was concurrent with his career, suggesting there were a number of other coaches and defensemen starting to make this a feasible shift. Regardless, no defensemen has ever played quite like Orr did since, and so that evolution never seemed to change the majority of play (aka even-strength play).
