James Harden is from L.A. and James Harden is a baller. Those two things mean that James Harden returns to L.A. every year to participate in the Drew League summer tournament. And this year, because he's one of the best players alive, James Harden led his team to the Drew League championship.
Harden played with the Los Angeles Unified team (LAUNFD for short), which is loaded with NBA talent, including former Rocket Cuttino Mobley acting as the resident Uncle Drew, Dorell Wright and Jerome Jordan. The team was started by four high school teammates from legendary Westchester High School (fun fact: they were also teammates of Trevor Ariza).
But, in the finals against a team with Swaggy P (née Nick Young) and Demar Derozan, the Players Choice MVP scored 37 points and sealed the deal with just over 30 seconds left.
LAUNFD won the game, 98-93, and claimed the trophy. Here's another angle:
DeMar DeRozan threw down a nasty alley-oop over James in the course of the game, but highlights don't win championships. Championships win championships.
