Miles set franchise marks with 3-pointers in a game (10), 3-point attempts in a game (14) and 3s in a half (eight). He also tied the record for most 3s in a quarter (five) and matched Brooklyn Nets guard Joe Johnson's NBA high for made 3s in a game this season.
"They were looking for me," Miles said. "I knew what the franchise record was, but I didn't know I was that close."
Miles knew he was getting close to the record when teammate Jarrett Jack informed him coming out of a timeout.
"The big guys were screening for me," Miles said. "Other than that, it was just like practice."
The Sixers were hammered on back-to-back nights.
The Cavs (12-23) set a season high with 29 assists. Kyrie Irving, playing in his first game in January, and Dion Waiters each dished out a game-high eight assists. For Waiters, that was a career high.
Brown said Miles' shooting was fun to watch.
"We called C.J.'s number quite a bit tonight," Brown said. "It was beautiful basketball to watch."
Varejao is averaging 16 rebounds in his last four games.
"When you're moving the ball like that, you're going to get some easy layups," he said. "I'm just shooting the ball with confidence."
The 6-foot-11 center made 8 of 10 shots from the field.
Sixers forward Thaddeus Young, an 18-point scorer, was held scoreless.
"It's just one of those games where you couldn't get it going," he said. "You just want to put it behind you and move on.
"As a team, we didn't play well. I think the road trip kind of caught up with us a little bit."
