I mean the usage rate was one of the main reasons in how Paolo won ROY last year, so it's not surprising that it's being used again with Wemby this year.When you need to push a narrative, and hype players, simple bring up useless stats.
Usage rate on a team with the worst record in the Western Conference and 3rd worst record in the NBA means absolutely nothing. The Spurs also have the 6th worst scoring defense.
Wemby is talented, no question. But using meaningless stats to hype him up is stupid. The NBA wanted him to go to the Spurs, a small market team with an aging coach and zero talent, so deal with it.
