This is from an interview with John Hollinger that appeared in The Athletic
JOHN HOLLINGER: Incorporating a high-usage piece is always a lot more complicated than incorporating a role player, because inevitably, they are going to displace a lot of possessions that were formerly used in different ways.
That said, I still think the Wizards can have a lot of offensive success while playing to Wall’s strengths. While Washington ran more stuff that allowed secondary players to thrive, one of the big reasons the offense improved so much wasn’t just the structure. It was the fact that they acquired a guy who can reliably hit from 30-plus feet off of pin-downs. Beal and Dāvis Bertāns were essentially the story of Washington’s offense, with a nudge from the Thomas Bryant-Moe Wagner center combo. The other guys weren’t major factors.
Any time Bertāns or Beal were off the court, the offense was pretty miserable (104.8 points per 100 possessions without Beal, 106.5 without Bertāns), but the Wizards scored at a fire emoji-worthy 118.7 per 100 clip with both playing, according to NBA.com.
Assuming that Bertāns re-signs, that element isn’t going away, and the floor will be a lot more open for Wall to do his thing anytime Bertāns is out there with him. Of course, one of Wall’s best skills has been the ability to generate 3-point shots for teammates; having shooters like Beal, Bertāns (and of course Garrison Mathews!!!) surrounding him should only make him more dangerous.
