As New Jersey-bred rocker Jon Bon Jovi tries -- unsuccessfully -- to convince Bills fans that he and his Toronto business partners won't move the team out of Buffalo if they win a bidding war, one-time Atlantic City casino mogul Donald Trump is trying to convince Bills fans that he's still a rich guy.

During the broadcast of the Hall of Fame Game between the Bills and Giants on Sunday night, NBC play-by-play announcer Al Michaels revealed what Trump had told him -- and, knowing Trump, a showman and media manipulator, he wanted Michaels to pass along the details to the rest of the world.

“He said he offered $1 billion. All cash, no contingencies, immediate closing. He’d have the check in one hour,” Michaels said. “He was a little miffed that it went out for bid again.”

The Wilson family, which is selling the franchise after the death of former Bills owner Ralph Wilson, already has a stronger bid on the table by Buffalo Sabres owner Terry Pegula, according to reports. And now is the time when the real interest of prospective owners or ownership groups is determined -- as they start bidding against each other.

The initial bid -- like the first poker chips in Texas hold 'em -- merely gets them into the game.

In the end, Trump might be supremely miffed, because his chances of owning an NFL team could be a long shot, given that he was a moving force in the USFL's antitrust lawsuit against the NFL in the 1980s.
