As potential ownership groups make their pitch for the Bills, Pegula has emerged as a favorite to purchase the team after meeting with members of the Bills' current ownership group.
Graham also reports that the group led by musician Jon Bon Jovi is "unfocused and disorganized."
Pegula, Bon Jovi and billionaire Donald Trump have bid on the franchise, which was put up for sale after longtime owner Ralph Wilson died in March at age 95.
Forbes estimated earlier this year the Bills are worth $870 million.
