The promoter being sued by Drew Brees' charitable foundation says it was Brees — not the firm — that failed to meet obligations involving the NFL quarterback's signature celebrity golf tournament.

San Diego-based Integrated Sports Marketing is challenging the foundation's lawsuit, which claims the company mismanaged the tournament. The foundation calls allegations in the company's new legal filing baseless.

In the court filing, the promoter portrays Brees as an absentee caretaker of the tournament, which has raised hundreds of thousands for local charities. Brees, ISM states in the motion, failed to meet his agreed-upon duties.

"For example, Mr. Brees failed to attend in any year the press conference at the Rady Children's Hospital kicking off the tournament; failed to participate in a single round of golf to promote the tournament in any year; failed to show up at the Celebrity Poker Championship; and refused or failed to show up at scheduled sponsor appearances, among many other things," the response states.

ISM officials say that the firm repeatedly brought in thousands more dollars than required under the contract.

The company claims it paid the foundation more than $189,000 for the 2011 tournament, exceeding the contracted amount of $110,000. In 2012, the company claims, the company guaranteed it would pay $125,000 and generated $321,000 for the foundation.

The Brees Dream Foundation filed a lawsuit in December claiming the ISM cheated the foundation and its charitable interests out of thousands of dollars through a series of schemes such as overcharging guests for hotel rooms, cutting side deals with vendors, manipulating ticket sales, failing to maintain books and reneging on paying appearance fees to some celebrities and prizes to some contestants.
