He had a decent season in Italy, but I think the main reason is that he gets rewarded for helping the team in qualifiers at several occasions and was also in Team Select (for the same reasons) last year.
Besides that I would like to see more known defenders in the Team Select to make things more competitive for Team USA. Only Suggs was part of an all defensive team last season and from the other players I guess only Keegan (known only to Kings fans and not NBA overall about his defense) and Thompson are good defenders.
