Varejao said he never gave much thought to matching Rick Roberson's club record against Houston in 1972.
"I never thought much about it," Varejao said. "It feels good. The most important thing is the win. I still don't know how we won this game."
Neither could the 14,248 brave fans who battled the extreme elements to get to the arena.
"There were a lot of people who left and thought the game was over," Cavs guard Jarrett Jack said. "It turned out to be a crazy, ugly (butt) 'W.'"
Magic guard E'Twaun Moore missed two free throws with 9.3 seconds left.
Once the Cavs (11-21) got into overtime, they outscored the Magic 8-2.
"We found a way to win," Cavs coach Mike Brown said. "It was exciting getting stops instead of trying to outscore everyone. When you allow two points in overtime, you're doing something right. It's great that our guys saw that we don't have to score to win games."
"Some people counted us out," Waiters said. "We're still learning how to close out games. One thing about the NBA, it's never over until there are triple zeroes (on the clock)."
"In that situation, I don't know what I'd do," Waiters joked. "That's what Delly does. He plays every game like it's his last."
The game was ugly, just as Brown likes it.
"Our guys never gave up," he said. "They kept fighting and fight. A lot of NBA games come down to one- or two-possession games. Our guys never quit."
Magic coach Jacque Vaughn lauded the Cavs for not giving up.
"You have to give them credit for continuing to play throughout the course of the game, all the way to the end," he said. "This one is going to sting a little bit. The guys played well enough to win the basketball game."
NOTES: The first two picks in the 2013 draft, Anthony Bennett and Victor Oladipo, struggled in Thursday night's game. The Cavs' Bennett, the top overall selection, missed all four of his shots from the field. Oladipo missed his first three attempts before he scored with eight minutes remaining. He finished with six points, four rebounds and two blocks. ... Cavs G Kyrie Irving missed his first game of the season with a left knee contusion. Luckily for him, there was no structural damage. He's listed as day to day. "You'd love to have him," Cavs coach Mike Brown said. "He understands what he needs to do to take care of his body long term and not worry about the short term." ... Veteran Jarrett Jack made his first start since signing with the Cavs last summer. Irving started the Cavs' first 31 games of the season. Jack leads all Eastern Conference reserves with 3.7 assists per game. "He'll do whatever the team needs to get the job done," Brown said. ... Magic C Nikola Vucevic sprained his left ankle in the Golden State game and was held out of Thursday's game. The 7-footer has 16 double-doubles this season, including one 20-20 game. He's averaging 13.4 points and 11.1 rebounds. Jason Maxiell started at center for the Magic. ... The Magic are expected to waive F Hedo Turkoglu by Jan. 7, league sources say, or possibly include him in a trade.
