It’s probably best to let Jennings explain it in his own words. From Twitter:
Jennings is clearly referring to the time Russell posted a private recording of Lakers teammate Nick Young to Snapchat. That recording appeared to implicate Young’s alleged infidelity to then-fiancee Iggy Azalea. Russell was “frozen out” by his teammates for some time, and later apologized.
Looks like there won’t be any love lost when the Knicks and Lakers meet for the first time this season on Dec. 11.
