CLEVELAND — Johnny Manziel has sought help to change his off-field lifestyle. Following a rough rookie season in the NFL, Manziel has entered a treatment program for unspecified reasons, an adviser for the Browns quarterback said in a statement released by the team on Monday. "Johnny knows there are areas he needs to improve on to help him be a better family member, friend and teammate, so he decided to take this step in his life during the offseason," Manziel adviser Brad Beckworth said.
