Four questions as we count down to kickoffs

HOUSTON -- Four questions on my mind as we get ready for Sunday kickoffs ...

Will Vincent Jackson be an X factor for San Diego?

I’ve read that he’s right back where he left off with Philip Rivers. The Chargers' passing offense has been plenty potent without him. Now the Colts have to find a way to make sure that connection doesn’t hurt them. Kelvin Hayden, Jerraud Powers and Jacob Lacey need a strong performance in the defensive backfield and early pressure from Dwight Freeney and Robert Mathis can do a lot to take the pressure off the corners.

Can the Jaguars perform in bright lights, big city?

Jacksonville is probably the league’s most anonymous team in the league. But a game as the AFC South’s first-place team against the Giants in New Jersey is a big deal. If Terrance Knighton and Tyson Alualu can stuff the middle and the Jaguars can slow Brandon Jacobs and Ahmad Bradshaw with the sort of run defense they’ve played the past couple weeks, those defensive tackles will gain some notoriety.

Will Joel Dreessen be the next tight end to shred the Titans?

Tennessee has struggled to cover tight ends and the Texans know how to use theirs, even without the injured Owen Daniels. Houston needs to get Dreessen in the flow and do whatever it can to test the coverage capacity of the Tennessee linebackers. Mid-range stuff over the middle is open way too often. Don’t over think it, Texans. Find the space and attack it.

Can Cortland Finnegan slow Andre Johnson?

Finnegan works to get under a receiver’s skin. Johnson is largely unflappable. The Titans’ lead cornerback was moved to the right side where he faces more top receivers. He did good work against Miami’s Brandon Marshall. But today starts a six-week stretch during which he sees both Johnson and Reggie Wayne twice. If the Titans are going anywhere, Finnegan will have to be at his best.
