Former Cal football coach Mike White called it "the biggest secret in the history of college athletics."

Even White didn't know during the fall of 1976 that Joe Roth, his All-America quarterback, was playing out his senior season while battling an aggressive strain of malignant melanoma. By February 1977, just 21 years old, Roth was dead.

Roth's remarkable tale -- the way he lived and the way he died -- unfolds in "Don't Quit: The Joe Roth Story," a documentary film five years in the making by Cal grads Phil Schaaf and Bob Rider.

The 85-minute film, which made its debut in April at the Newport Film Festival, had its first Bay Area showing Wednesday night in front of about 300 people at Memorial Stadium.

"In the end it has nothing to do with the sport," Schaaf said. "Instead, it's about human elegance in the face of unfathomable adversity. In Joe's case, it's against this backdrop of athletic greatness."

Roth's cancer didn't become public news until after the season.

Lena Roth, who wrote a book about her son in 1984, said Joe just wanted to be like everyone else. "But he was different," she said.

Schaaf said he expects "Don't Quit" to be released in the fall during football season, although the filmmakers still are negotiating with various outlets. For updates on distribution plans, go to www.JoeRothfilm.com.

NBA

Former Archbishop Mitty star Aaron Gordon had seven points and eight rebounds in 31 minutes, but Orlando fell to Boston 76-67 at the Orlando Summer League. It was a big improvement over Tuesday's game when he failed to register a field goal, rebound or assist.

"I was trying to be more active. I'm going to continue to stay confident and continue to shoot the same shots and just shoot them better,'' said Gordon, who was the Magic's first-round draft pick after one season at Arizona.
