“I think the opportunity in the end was too hard to pass up,” said Broekhoff, who spent five seasons playing in Europe before signing a two-year deal with the Mavs on Aug. 6, 2018. He couldn’t pass up the chance to work with Brown, who in November started his second stint as the Australian national team coach. Broekhoff and Sixers point guard Ben Simmons are expected to play for the Boomers in the 2021 Olympics. But there’s another incentive for playing this summer. “I still feel like I’m on the cusp of finding somewhere steady in the NBA,” Broekhoff said, “and hopefully that will be Philly.”
