Mangini is just 10-21 in two seasons and could be heading into his final game Sunday. The Browns (5-11) host the Pittsburgh Steelers (11-4), who can win the AFC North with a victory.
Mangini acknowledges the uncertainty and said Friday he feels good about a lot of things the Browns have done. He says the team has a "really bright future, and I'm excited to be a part of it."
Holmgren has never ruled out a possible return to coaching. He wanted to see improvement this season after keeping Mangini following a 5-11 season in 2009.
