Heading into Sunday night's game, the Sixers averaged 17.2 turnovers and had their shots blocked an average of 7.4 times a game. They ranked a distant last in the NBA in both categories.
Brown's team was also last in scoring defense (110.0 points a game), opponents' assists (26.6), and three-pointers surrendered (9.5).
"Everybody gets tired of me talking about the defensive problems that we have," Brown said. "At times when you dig a little deeper, you've got [point guards] Michael [Carter-Williams] and Tony [Wroten] driving at the rim. They get their shot blocked, and off they go."
The same thing happens with quick shots. The Sixers throw up ill-advised shots early in the shot clock. The opposing team grabs the rebound and starts a fastbreak.
"It gets deflating, and people aren't even in position," Brown said. "[Opponents] are not expecting somebody to shoot."
Sunday's game marked this season's second homecoming for Sixers rookie Hollis Thompson. The 6-foot-8 swingman was born in Pasadena, Calif., and attended Loyola High School in Los Angeles.
He said he grew up rooting for the Clippers and the Lakers.
"Clippers games were a little easier to get [tickets] to," Thompson said. "So I've been to more Clippers games. But I was a big Lakers fan, too."
The Sixers defeated the Lakers, 111-104, at the Staples Center on Dec. 29.
