They don't call it the preseason for nothing, folks.
The season before the real season allows NBA players to hone their skills before meaningful games take place. So, the same pass should be given to mascots, who aren't exactly in midseason form yet, either.
Seen here is BrooklyKnight, mascot of the Brooklyn Nets, trying and failing to execute a dunk where he jumps off a trampoline and over some cheerleaders. During the regular season, we have to believe he converts, but because it's only October, and perhaps because he ate some popcorn beforehand, BrooklyKnight fails miserably, much to the amusement of the rest of us.
