Can such an nba international player lineup win the championship?

This is entirely possible. There are many international players who are very strong. Far away, just count the teams that have entered the league since Yao Ming. The point guards are Nash, Parker, Calderon and Lu Biao. Shooting guards Ginobili and fournier. Small forward letter brother, batum, aminu, Wiggins. Power forwards Scola, Nene, Polzingis, Nowitzki, Split, Ibaka and Gasol. Center Yao Ming, Vallejo, Noah and Bogut. If these people randomly team up to join the NBA, it is still very powerful. A strong contender for the championship.
