Brett Brown left the highly successful San Antonio Spurs to become head coach of a drastic rebuilding experiment with the Philadelphia 76ers.

The 76ers finished 13-14 with the second worse record in the NBA and are expected to struggle again to produce wins this season.

“It is frustrating at times,” said Brown. “We won 50 games every single one of my years in San Antonio. All 12 of them. The motivation I have is I see a big, bright light at the end of all of this. I see daylight. I see Embiid getting healthy. I see some more draft picks coming. I see Nerlens getting older. I see an abundance of money, flexibility to look at free agents. I see daylight.

“For me, it’s about putting the building blocks culturally in place. We have to get our culture right so that when we get these pieces, the foundation is strong enough to grow them.”

The 76ers are hoping Nerlens Noel, Joel Embiid and Michael Carter-Williams can develop into All-Star caliber players.

“I feel that trying to coach myself with a very, very long lens is important,” Brown said. “I see daylight in this program. Michael’s 3-point shot, Nerlens’s progression at the foul line, Tony Wroten’s assist-to-turnover ratio, all those types of things are development things that are our measurements this year. That’s our report card and it’s done with a very long lens.”
