The Browns finished the campaign with a 41-9 drubbing by the Pittsburgh Steelers.

"Although we have made improvements this season, my responsibility is to ensure that we establish a program that will allow this team to compete at a championship level," Browns president Mike Holmgren said in a statement.

"That will continue to be our goal in everything we do."

The Browns registered upset victories this season over the playoff-bound New Orleans Saints and New England Patriots but failed to follow up in finishing 2-6 with losses in their last four games.

Mangini, who previously coached the New York Jets, thanked the Browns owners for the opportunity to coach in Cleveland.
