Currently Detriot has an active 21 game losing streak and San Antonio's is 18 games. Based on some quick research, the previous record for the second longest active losing streak was 15, on Feb 13, 2019 when the Knicks were a day away from ending an 18 game losing streak, while the Suns were at 15 games in a streak which would eventually reach 17 games. We're witnessing history, folks.
