He also ran for 19 yards on 4 carries.Sanders led three touchdown drives, showing composure under pressure, good movement and accurate throws, including a 25-yard pass to Brenden Bates.Both Ward and Sanders have trained under QB coach Darrell Colbert Jr., but Ward’s $43M rookie deal has put him ahead in the spotlight.
