Cleveland owner Jimmy Haslam says the Browns have told Johnny Manziel to start acting "like a backup quarterback." Haslam praised Manziel for being an "ultracompetitor" but reiterated that Brian Hoyer is the team's starting quarterback and Manziel will have to beat out the veteran in training camp. Haslam made it clear that Manziel "is not the starter. Johnny's the backup." Haslam spoke on Manziel while addressing a luncheon in Canton, Ohio, at the Pro Football Hall of Fame. The owner said the team was not scared off by the celebrity that comes along with Manziel, adding that the Browns told Manziel "this is not Hollywood" and that he will have to come to Cleveland ready to work hard. Manziel's new teammates are happy to have him, but they're not ready to anoint him as the Browns' starter at quarterback. "I think good old Johnny Football is going to be a good addition to Cleveland," center Alex Mack said Monday. "Don't know who the starter is going to be, though." "Coach [Mike] Pettine talked about drafting competition, and I think he stuck to that," tight end Jordan Cameron said. "It seems like it's going to be a lot of competition. We'll see how that battle goes." Players spoke before the 15th annual Cleveland Browns Foundation Golf Tournament, which identified education for Cleveland youth as its mission this year. Players on hand acknowledged that Manziel brings a ton of excitement to the team and city, but they were not assuming native son Hoyer's days as the team's No. 1 were already done.
