Teams often look for ways to personalize players and make them more relatable. Here the Blazers use broadcaster Lamar Hurd with the players to tell jokes to try to make each other laugh. Great in-game content, easily adapted to social content as well.
Fans get to know the players (and broadcaster) and, of course, everyone gets to share in a laugh.
Great use of their talent as well, clearly Lamar has a good relationship with the players and is able to get the most of out them.
