Having made no secret of wanting a strong, veteran presence behind Tony Romo as the team's backup quarterback, the Dallas Cowboys reached an agreement with Kyle Orton on a three-year contract, a league source said Wednesday. Orton, 31, has started 69 career games for Chicago, Denver and Kansas City and has 80 touchdown passes and 57 interceptions. He is 35-34 as a starter but struggled in Denver with a 4-9 record in 2010-11.
