Sources believe there is virtually no chance Mario Manningham will return to the Giants for the 2012 season. Manningham, one of New York's Super Bowl heroes, is expected to follow former Giants assistant Mike Sullivan to Tampa Bay. Sullivan, who was the quarterbacks coach with the Giants, has been named the offensive coordinator of the Buccaneers. Giants general manager Jerry Reese recently conceded that there's a "75 percent chance" Manningham won't return to the team.
