The Cleveland Browns brought undrafted rookie QB Graham Harrell in for a tryout.  He left Berea without a contract but the Browns liked what they saw.  Harrell didn’t have much of a chance to unseat Brady Quinn, Derek Anderson or Mangini favorite Brett Ratliff for a spot on the roster.  If one of the QBs is injured or traded the Browns probably wouldn’t hesitate in bringing Harrell back into the fold.  Harrell looks the part as he stands 6′2″, 217 pounds.  He played in 44 games (38 starts) in four years at Texas Tech.  He completed 1,403 of 2,011 passes (69.8%) for 15,793 yards with 134 TD passes and only 34 interceptions at Texas Tech.  The Browns will keep Harrell’s phone number on speed dial in case the need for him arises.
