Yes, that was 20-year-old, third overall pick (2016 draft) Jaylen Brown you saw playing a lot of point guard during summer league games in Utah and Las Vegas. Why all the ball handling for a 6’7” top prospect considered a natural small forward? Prior to summer league, the Celtics signed Gordon Hayward and drafted Jayson Tatum, that’s why. In addition, Avery Bradley was sent to Detroit to clear up contract room for Hayward. That means the Celtics are stacked at small forward, but have open minutes at shooting guard. Brown already received 15-plus starts at shooting guard last year when Bradley was injured, so this isn’t really a position switch for Brown. Plus, Coach Brad Stevens has said he doesn’t see traditional positions, instead relying on “a ball handler, a wing or a big”. That may be especially true for Brown, who could occasionally set up plays or square up for corner threes on offense, while trying to stop the likes of LeBron James on defense. The big question is will Brown or Marcus Smart get the start at shooting guard. Smart is atop the depth chart now due to seniority. But Stevens really likes bringing Smart’s defense and post-up offense off the bench, taking advantage of backup opponent mismatches. Brown is also a much better catch-and-shoot option than Smart, which is helpful when fellow starter Kyrie Irving is on the floor. That thinking means Brown has the long-term advantage towards gathering more starts. In addition, the three for one Irving trade with Cleveland weakens Boston’s depth. Whether starting or coming off the bench, expect Brown’s minutes to greatly exceed last year’s 17.0 minutes per game. The ceiling is high for Brown. It will be interesting to see how Stevens balances striving for the Finals while also developing young stars Brown and Tatum.
