Potential suitors for the Pittsburgh Penguins began examining their options over the weekend following Canadian billionaire Jim Balsillie's sudden withdrawal from a proposed deal to buy the NHL club. Frank D'Angelo, the colourful Toronto businessman behind Steelback beer whose bid for CFL franchise in Ottawa was recently turned down, said Sunday he and billionaire partner Dr. Barry Sherman were considering making an offer. Dallas Mavericks owner Mark Cuban is also believed to have renewed interest in looking at the club and Balsillie, co-chief executive officer of BlackBerry maker Research In Motion Ltd (TSX:RIM), also remains in the picture despite pulling the plug Friday on a deal for the Pens reportedly worth US$175 million. D'Angelo, Sherman and a team of their financial advisers spent the day developing models for a possible offer and the infrastructure of how they would operate the franchise. They hope to secure a meeting with Penguins president Ken Sawyer next week. "It's hard to understand what you're up against until you've seen all the numbers," D'Angelo said in an interview with The Canadian Press on Sunday. "We just finished a meeting now, putting together a business plan."
