CLEVELAND — Freddie Kitchens had something on his coaching r?sum? no other candidate could match. He made Baker Mayfield a better quarterback. Kitchens, who helped Mayfield turn his rookie season into a record-breaking one during an impressive eight-game stint as the Browns offensive coordinator, was named Cleveland’s 17th full-time coach on Saturday, capping a remarkable personal rise up the coaching ranks. His next goal: Take the Browns where they’ve never been — the Super Bowl. “It’s an honor to be named the head coach of the Cleveland Browns,” Kitchens said in a release.
