CLEVELAND — Eric Mangini has given Cleveland’s new boss more to chew on.

Jerome Harrison had 148 yards rushing and the Browns won their third straight, 23-9 over the Oakland Raiders on Sunday, extending a surprising streak that Mangini can use to strengthen his case to Mike Holmgren that he deserves to remain Cleveland’s coach.
With consecutive wins over Pittsburgh, Kansas City and Oakland, the Browns (4-11) have their first three-game winning streak since 2007 and only their third since 1999. Holmgren, who is expected to be introduced as Cleveland’s team president this week, may have to factor Cleveland’s late-season surge into whether he retains Mangini, once given little chance of staying after a 1-11 start.
