We won't get to see LaDainian Tomlinson or much of Shaun Alexander tonight, but there are a few players to keep a close eye on during the Sunday Night Seattle-San Diego tilt. These aren't all sexy storylines, but preseason action is for the diehards.

1. Craig Davis- San Diego is expecting this surprise first-round pick to step up into a starting role with Eric Parker hurt. There are mixed scouting reports on Davis, but he has impressed in camp when healthy. Like most rookie receivers, we're skeptical about his value in fantasy leagues.

2. Hackett vs. Burleson - D.J. Hackett has earned the starting job opposite Deion Branch with his strong play the last few years. But former Viking Nate Burleson has reportedly had a strong camp and is challenging for snaps. Hackett owners shouldn't worry too much, but Burleson could wind up taking playing time from slot man Bobby Engram.

3. Third Running Backs - Both these teams are thin at running back, and it's uncertain who will claim the third running back spots. Darren Sproles needs a good preseason to keep his NFL career going for San Diego. Leonard Weaver and Marquis Weeks are battling for the Seahawks.

4. Young backup quarterbacks - Charlie Whitehurst for the Chargers is trying to show growth in his second season so he can pass Billy Volek on the depth chart for good. If David Greene of the Seahawks shows something in the preseason, backup Seneca Wallace may play more at other positions.

5. Diamonds in the rough - This are important games for unheralded receivers. I've heard Legedu Naanee from San Diego has some impressive physical skills. Courtney Taylor and Ben Obomanu have some long-term potential in Seattle.
