Big Baby Davis Played in The Crew League in a Very, Very Tight Uniform

There is a video making the rounds right now that shows Glen "Big Baby" Davis playing basketball in a very small outfit. It is mesmerizing. I've watched it a dozen times and just have so many questions.
Big Baby still got it ?

The main question, of course, is huh?
Where is this? Where are all the masks? Why are those clothes so small when Big Baby is so... large?
After a bit of research I have learned that this video is from a game in The Crew League. It's a 4-on-4, full court basketball tournament consisting of hip-hop artists and their crews. Apparently, Big Baby counts as part of someone's crew. I guess when $100K (for charity) is on the line you start hanging out with as many former NBA players as you can.
As for his fit... This has to be a choice. It looks like he's wearing boxer briefs and a halter top. You have to be comfortable in your own skin to pull that look off in a crowded gym.
And speaking of the crowded gym, what's the deal with The Crew League COVID protocols? Best not to consider it I guess. Instead, here's another angle which Davis posted on his Instagram with the caption, "THE THREADS CAN'T HOLD ME."
Maybe unsurprisingly, the team that featured Davis won the tournament. Big Baby was a member of the Firefighters, a team captained by Swae Lee. So congratulations to everyone involved, but especially whoever was in charge of handing out uniforms.
