— Tim Donaghy says he doesn't bet on basketball anymore.

But basketball gambling is what pays his bills these days.

Like a recovering alcoholic tending bar for his old drinking buddies, the ex-NBA referee has been breaking down game tape and analyzing point spreads for a shady sports handicapper in Allentown, Pa., known as "Danny B," who uses the information to sell gambling tips to his clients.

"Meet the man who generated millions of dollars betting on basketball, as seen on '60 Minutes' and documented by the NBA and FBI," Danny B.'s website, sportsconnectionwins.com, says of Donaghy.

"It's basically a consulting firm," said Donaghy, 45, who's still on probation for gambling on basketball games and providing picks to two co-defendants while he was an active referee. He resigned in 2007 after 13 years in the league and pleaded guilty to federal gambling and wire-fraud charges in New York. He served about 13 months in prison.

Donaghy's current employer is known in the gambling industry — and apparently to Donaghy's probation officer — as Danny Berrelli. But his real name is Daniel T. Biancullo, a North Jersey native with a 2004 federal conviction stemming from his role in a Florida sports-gambling operation that counted ex-NHL player Jeremy Roenick among its clients.

Last week, Biancullo, 49, confirmed his "real" identity, saying he'd been using Berrelli as a "stage name" for years.

"Hiding names, aliases, it's all part of the business," he said. "This comes back to me protecting my kids."

Donaghy, who is prohibited from associating with felons while on probation, said he wasn't aware of Biancullo's conviction until informed by the Daily News.

"As long as it wasn't molesting kids," Donaghy said. "I'm nobody to judge anyone."

Donaghy's probation officer in Sarasota, Fla., where he lives, apparently was under the impression that Biancullo's "stage name" was his real name.

"We are investigating the true identity of Danny Berrelli," said Steve Beasely, Deputy Chief U.S. Probation Officer for the Middle District of Florida, said Monday. "We were not aware that Danny Berrelli had any other name."

Biancullo was among a crew of Florida-based sports handicappers, or "touts," who pleaded guilty in 2004 to federal gambling charges for falsely claiming to have inside information about games and referring callers to offshore casinos in exchange for kickbacks.

The Philadelphia Inquirer reported then that federal authorities caught Biancullo on tape telling one caller: "When you're paying guys to throw a game, when you're paying officials to make bad calls, you know it costs a lot of money. There's a lot of money at stake here. Millions and millions of dollars. So that's why the cost is so great."

Roenick, who never was charged with a crime, acknowledged that he was a client of the firm Biancullo worked for. He told the Inquirer in 2004 that he considered them "scam artists."

"Honestly, they lie like (bleeping) rugs," he told the newspaper.

When asked last week about his past legal troubles, Biancullo said he'd gotten "caught up in a bad thing." He was sentenced to six months home detention and three years probation.

"I'm not a saint. I'm not a (bleeping) choirboy," he said. "I'm sure people are going to take shots at me. I don't give a rat's ass. I'm a survivor. I've been around the block more times than a space shuttle and I've survived."

Biancullo and Donaghy, who started working together in October 2010, say their current operation is entirely above-board.

"Who do you want to pick your NBA games, a plumber down the block or a former NBA referee? I'll go with the former referee," said Biancullo, who said he's paying Donaghy about $50,000 a year, including car payments.
