You may not know this, but guard Rajon Rondo is incredibly, ridiculously talented at the game of Connect Four. Hall of Famer Isiah Thomas was on the losing end of a series of contests captured by NBA TV on Facebook while Greg Anthony watched:

Yes, the video is around nine minutes long, but you can watch highlights including Anthony try to jump in and try to show Thomas a move he should have made and then figure out Rondo would have beat him anyway.

Rondo’s incredible Connect Four skills were spotlighted in an ESPN The Magazine feature in 2015:

Still, as much as Rondo wanted to win, he loathed defeat even more, a competitiveness that found an outlet in all things — great and small — but most famously in the game Connect Four. Rondo would play on their porch, decimating friends and family deep into the night while his mother worked the graveyard shift at the Philip Morris factory to support her four kids. “If you did win once, he would beat you five or six more times to let you know he was the best,” says Dymon, his younger sister. (Rondo’s Connect Four prowess has since become legendary and has made for heartwarming-yet-awkward community outreach moments. The day he was traded to Dallas in December, he spent his final hours as a Celtic at Boston Children’s Hospital, crushing all comers in the game, repeatedly telling kids, “No mercy.”)
