At the Mavs Ball, Flagg offered a private meet-and-greet and game day experience for bid, while Thompson and Max Christie teamed up on a round of golf at the PGA headquarters in Frisco — an item auctioneer Dean McCurry doubled on the fly, ultimately raising $80,000 for the foundation. That back-and-forth was on full display throughout the live auction, with players and fans trading bids and pushing totals higher with each item.  The team’s largest fundraising event of the year once again delivered — raising nearly $1.5 million for the Mavs Foundation.
