Originally Harrell agreed to a tryout with Dallas before agreeing to terms with the Browns.
After leading the Red Raiders to an 11-2 record in 2008, Harrell received several honors, including the Johnny Unitas Golden Arm Award, which is given annually to the nation's top senior quarterback.
He also was named an AFCA first team All-American and Co-National Player of the Year by The Sporting News. Harrell was a finalist for several other awards, including the Heisman Trophy (fourth), Maxwell and Davey O'Brien.
"Harrell displays patience in the pocket, a quick release and a great sense of timing," notes NFL draft expert Chris Steuber. "He goes through his progressions consistently and locates the open receiver quickly.
"He's also extremely accurate on intermediate routes and has nice touch on vertical routes."
Harrell is the Red Raiders' all-time leading passer with 15,793 yards, which is second on the NCAA's all-time list. He is the only player in NCAA history to pass for 5,000 or more yards in two seasons after completing passes for 5,111 yards in 2008.
