Team USA star Kemba Walker has heard the question plenty these past month, now the time has come for him to start providing an answer.

Since Team USA have named their squad for the FIBA World Cup, the critics have labelled them many unflattering terms due to the large number of NBA superstars and stars who opted against playing this year.

Worst USA team ever, USA D team and other titles have been thrown around and while this is the lowest-profile group of of NBA players to wear USA colours, Walker knows his team can still win the world cup.

Those armchair critics have forgotten the USA couldn't field any NBA players in 1998 due to the NBA lockout so sent players of overseas imports, while before the 1992 Dream Team only “amateur” college players were eligible.
