Because there wasn't a single All-NBA player representing the USA at FIBA and they had no idea how to play together while international players have their own local systems they've been building together for years.
I mean, who are you even disappointed with from the FIBA tournament. Brandon Ingram? Cam Johnson? Paolo Banchero? I don't think there was a single player on the team who had a meaningful history of playoff success. The USA practically sent a U-25 squad of inexperienced, third-tier players with no real leadership or chemistry at all going against a lot of seasoned pros who had been there before.
Nah nah nah nah nah. The ludicrous argument stated in the idiotic video OP posted and the clowns in this thread are parroting is that the talent level is sOoOoO high now that MJ would be a borderline roleplayer in this age/not even top 10. Why did the coli favorite "future face of the league" Ant Edwards led team go out like bytches in FOURTH PLACE at a FIBA cup??? How come "best defender in the league" JJJ, the most emblematic player of this "new wave" of centers that guard all positions while spacing the floor supposedly look like a make-a-wish kid in an international setting? How come the "best PG in the league" Haliburton stuffing all the empty stats in the NBA regular season with triple doubles/double digit assists 0 turnover games every week went out with multiple triple singles shooting 2/8 from the floor against juggernauts like GERMANY once he had to play with FIBA rules and refs??
These are the FACES of the MOST TALENTED LEAGUE EVER, where's the gold and accolades to show for all that talent that wouldn't even allow MJ himself a spot in the top 10 these days?? Surely it amounts to more than getting sonned by RJ Barrett (a "throwback to the mid range 90s stone ages" type player no less) in the 3rd place game???
