Yeah that PR team had enough size to not get obliterated on the boards / in the paint and Arroyo was an NBA caliber player. Just pointing out that winning the first game of the regular season isn't anywhere near the same as an elimination game.
Americans love to dismiss those rosters, but from 2000-2006 most of those players were all NBA, all Stars, all defensive, important players for their teams etc. Like Rj, boozer, Odom, all not good enough for the 04 team, but when rj came to the Spurs fans were busting a nut, boozer and Odom both played big roles on playoff teams that made deep runs, etc. Even Marbury who is so easy to laugh at and dismiss now, once upon a time he was a 2x all NBA, 2x all star. The 06 team too. Any one of those teams, 02, 04, 06, if they were NBA franchises they would be favorites to win in just about any NBA season, they came up short because of poor chemistry / fit and heroic performances in single game elimination from Argentina and Greece who in terms of talent, size, athleticism were thoroughly outclassed. The US always has a size / athletic advantage over other teams but 02-06 it wasn't enough, they weren't smart enough / played hard enough to make it count, add shaky shooting and single elimination and upsets happened.
