Not to worry, the team's clearly been getting better at defending Booker. Look how his stats have consistently dropped against Boston since his 70 point game:
70 on 3/24/17
38 on 12/2/17, 32 point decrease from previous game
38 on 11/8/18, 0 point decrease from previous game
25 on 12/19/18, 13 point decrease from previous game
Ever since the he dropped 70, he's averaging a 15 point decrease the following game vs the C'! If this trend continues, he'll only score 10 tonight!
