Team USA Roster:
PG: Stephon Marbury, Dwyane Wade
SG: Allen Iverson, Carmelo Anthony
SF: Richard Jefferson, LeBron James
PF: Lamar Odom, Shawn Marion, Amare Stoudemire
C: Tim Duncan, Carlos Boozer, Emeka Okafor
Coach: Larry Brown
Allen Iverson is not a top-tier player? He's one of, if not the best, defensive players in the league. The biggest problem with Iverson is the compatability issues with Coach Brown - and that's a weak excuse at this level. And in the Olympics no less.
Lebron and Carmello aren't top tier or at least top tier? Or at the very least heir apparent? Carmello was the top college draft pick with game and heart. Lebron is a man among men in the league - and he's 18. (and believe me, I was waiting to see him get smacked on his ass, but he proved his worth/ability his rookie year).
