Matt Hasselbeck is expected to start Sunday's Week 5 game against the Vikings. Jake Locker hurt his left shoulder for the second time in four weeks. Hasselbeck started 16 games a year ago, averaging 223.2 yards to go with 18 touchdowns and 14 interceptions. His arm strength is really lacking at age 37, but the veteran reads defenses and feels out a pocket better than Locker. Considering the Vikings are giving up just 3.27 YPC on the ground this season, the Titans might be forced to go to the air. Hasselbeck is on the desperation QB2 radar.
