Among the candidates are Sherman; Dick Jauron, who served as the Detroit Lions' interim coach after Steve Mariucci was fired; and former Houston Texans coach Dom Capers. Former Packers receiver James Lofton, who played on three of the Bills' 1990s Super Bowl teams, also is a candidate.
Sherman would be an intriguing selection for Buffalo.
First, even with last year's 4-12 record which cost him his job in Green Bay, Sherman boasts a career record of 55-31. He sent four teams to the playoffs in his six seasons.
Second, while doubling as the team's general manager, Sherman considered drafting quarterback J.P. Losman in the first round of the 2004 draft. Sherman saw many similarities between Losman and Brett Favre. The Packers held the 25th pick in the draft, but Buffalo traded up into the No. 22 slot to grab Losman.
"I didn't have that choice," Sherman said on draft day. "If I had that choice, it would have been a tough call because I like Losman. But I like Carroll, too. I think Carroll can impact our team immediately. But I did like Losman, there's no question about that."
Third, Sherman could be able to recruit Jim Bates to Buffalo to be his defensive coordinator.
