Ben Simmons did not crack a smile or pat himself on the back after the Philadelphia 76ers eliminated the Brooklyn Nets from the NBA playoffs.

The 22-year-old Australian knows three-time All-Star, two-time defensive player of the year and one-time finals MVP Kawhi Leonard and a talent-loaded Toronto Raptors are waiting for the 76ers in the eastern conference semi-finals.

The 76ers looked like legitimate championship contenders when crushing the Nets 122-100 in Philadelphia on Wednesday (AEST) to take the first-round series 4-1, but the Raptors pose a significant threat.

"We're trying to win a championship," said Simmons, remaining focused on the 76ers' ultimate goal.
