I discovered something a couple of days ago that I'm pretty excited about, but I'm not sure it's really new. If you go to a game's box score on NBA.com, some of the stats appear as links. Click on the stat, and you go to a page with video clips of each play. So, for example, if I follow the link to Jayson Tatum's assists against the Raptors, I get this.
So, if this is old news, I apologize. If not, I thought it worth sharing.
