If Giannis had a negative on/off differential per 100 possessions then sure I'd listen to arguments on that, but of course Giannis doesn't have a negative on/off differential, in fact it isn't close to negative at +7.0. Brown's is -2.7. In other words, Boston is better by 2.7 points per 100 possessions when Brown is on the bench. He also has the lowest +- per 100 of the top 7 when he is in the game at +4.8 (behind Smart, White, Tatum, Grant, Al, and Rob - Brogdon is the only consistent regular worse than Brown). There is years of evidence of this. It isn't new.
