The Titans believe Jake Locker has improved his passing accuracy after working with Matt Hasselbeck. The new and improved version will be on display Saturday night against the Vikings in the team's preseason opener. Even if Locker looks like the next Peyton Manning, it won't matter. Barring an injury to Hasselbeck, Locker is highly unlikely to start any games this season. That being said, it's good to hear the rookie is focused on improving his faults.
