The Los Angeles Lakers might be a dumpster fire right now, but that hasn't stopped fans from buying up all their gear ... with the Purple & Gold leading the NBA in merchandise sales this season.

The league just released its list of most popular fan purchases through the 2021-22 season so far ... and LeBron James sits at the top of the throne for player jersey sales, with the Lakers coming in at #1 for overall team merch sold on the NBA Store website.

It's pretty interesting, considering the Lake Show has stunk up the place this season -- they're 22-23 and head coach Frank Vogel is on the verge of losing his job.
