Tennessee's secondary: It's no coincidence that the Titans have recorded at least one interception in every game during its first 4-0 start in franchise history. Nick Harper was last week's star, picking off Gus Frerotte to clinch the game.
Big gains from Justin McCareins: The veteran wideout has yet to reach the end zone this season, but leads all Titans receivers with a 16.5-yard avergage on eight receptions. Over the last two weeks he has seven receptions for 127 yards and has been a reliable option for Kerry Collins.
Le'Ron McClain in the red zone: Various injuries have reduced Willis McGahee's carries over Baltimore's first three games, and his status for Sunday is uncertain due to a rib injury sustained against Pittsburgh. In the meantime, McClain has picked up the scoring slack, proving to be tough to stop in the red zone. Rookie Ray Rice will likely see more carries as well if McGahee is limited.
