Del Biaggio had entered an agreement two years earlier, in 2005, to purchase the Pittsburgh Penguins, but the club backed out of the deal after it won that year's NHL draft lottery and took Sidney Crosby with the first overall pick. On July 19, 2007, a group of local business owners known as Our Team Nashville held a rally at the Sommet Center to encourage fans to buy season tickets in order to help the Predators meet the attendance figures needed to keep the team in Nashville. They drew approximately 7,500 fans and sold the equivalent of 726 full-season tickets during the rally. The rally was heavily supported by George Plaster, then a sportscaster on WGFX 104.5 "The Zone" sports radio in Nashville. On August 1, 2007, the group released a letter of intent from Craig Leipold. After negotiations with the City of Nashville, the local group headed by David Freeman reached an agreement with Nashville Mayor Karl Dean, and the NHL Board of Governors approved the sale on November 29, 2007. The $172 million acquisition of the Nashville Predators included repayment of existing debt of approximately $61 million and $2.2 million in fees and expenses. The sale of the Predators to the Tennessee-based group included Del Biaggio, who had been trying to move the team to Kansas City. The locally based buyers held 73% of the team, while Del Biaggio and a minority partner acquired about 27% of the club. In June 2008, Del Biaggio ran into legal trouble over a multitude of unpaid loans, culminating in his filing for Chapter 11 bankruptcy. Furthermore, it was alleged that Del Biaggio acquired the loans he used to buy his stake in the team through fraudulent means, prompting an FBI investigation and criminal charges. The charges culminated in a 97-month prison sentence for Del Biaggio. Under United States bankruptcy law, a trustee was appointed to sell Del Biaggio's assets, including his stake in the Predators, to pay off his creditors. In November 2011, it was announced that Calgary businessman W. Brett Wilson had purchased a 5% interest in the Nashville Predators. On March 1, 2010, during the 2009–10 season, the Predators front office saw Freeman step down as chairman of the Nashville Predators in favor of Thomas Cigarran. On September 2,
