Honestly, I'm not surprised by it. We don't have the shooters we need right now. The International game is SO much different than the NBA. We play horrible defense, can't shoot the long-ball and had a very hard time adjusting to the zone defenses.
While most casual basketball fans will probably blast them, I don't think it's all bad. By the olympics we'll have had a lot more time to gel as a team and let the players work with eachother. They will also have better shooters like Ray Allen, Chauncey Billups and Mike Redd back if they choose to play.
