1. LaDainian Tomlinson is still explosive when healthy. Although his numbers were muted by limited playing time, he displayed the second gear that was missing for most of last season. His 8-yard catch on a screen pass and his 6-yard run over the left side -- which nearly went for much more -- proved he is still dangerous when given room.
2. Michael Bennett's ability to play special teams could make or break his quest for a roster spot. He made a nice play on the punt team to down a Mike Scifres offering at the 4-yard line midway through the first quarter of Saturday's game. However, he missed an opportunity to down a Truman Spencer punt in the third quarter and the ball rolled into the end zone for a touchback.

3. San Diego has four wide-outs in contract years (Vincent Jackson, Chris Chambers, Malcom Floyd and Kassim Osgood) yet has little reason to be worried -- there is an abundance of talent waiting in the wings. Second-year player Gary Banks (three catches for 31 yards) and undrafted rookie Charly Martin (five receptions for 67 yards) both appear to be keepers. Additionally, former first-rounder Buster Davis flashed his playmaking skills and racked up 154 all-purpose yards.
4. With the team's move to keep Tyronne Green at guard and play Scott Mruczkowski at center, the competitions on the O-line are over. The starters will be Marcus McNeill, Kris Dielman, C Nick Hardwick, Kynan Forney and Jeromey Clary. Also active on game days will be L.J. Shelton, Louis Vasquez and Mruczkowski. Green will make the team but will usually be inactive.
5. Charlie Whitehurst, entering the final year of his rookie deal, didn't do himself any favors with his three-turnover performance against the Seahawks. And in a weird way, that's fine with the Chargers. Whitehurst expects to test free agency next offseason in search of more playing time, while the Chargers would like to bring him back as the No. 3 QB. However, his poor ball security served as a reminder why the team felt compelled to re-sign Billy Volek after the 2007 season.
6. DE Vaughn Martin will be a part of the rotation by Opening Day. Martin played a full three quarters against Seattle, and despite his technique degenerating as the game wore on, he accounted himself well. Last year, the Chargers kept only five defensive linemen active on game days, which means Martin and veteran Ian Scott could be in an either-or situation. Also making some noise was NT Ogemdi Nwagbuo, who seems primed for another season on the practice squad.

7. Kevin Burnett may have gained some ground in his quest to win the starting inside 'backer job opposite Stephen Cooper. Burnett led team with six total tackles and did a nice job of sifting through the clutter inside. Dobbins finished with four tackles but continued his trend of struggling against the pass, often closing one step too late.
8. One of the best ongoing battles is between OLBs Antwan Applewhite and Jyles Tucker. Applewhite was more disruptive on Saturday, netting four tackles and an interception on a pass that was knocked into the air by CB Antoine Cason. However, Tucker had some big plays of his own, including dropping Seahawks RB Justin Forsett for a 3-yard loss late in the third quarter.
9. The competition at safety also ratcheted up a notch with backups Steve Gregory and Kevin Ellison both making big plays. Gregory delivered a punishing hit on WR Deon Butler early in the second quarter to force an incompletion on third-and-7. Ellison also laid the lumber when he turned Forsett head-over-heels with a punishing tackle-for-loss early in the third quarter.
10. Scifres picked up right where he left off last season. His first three punts pinned the Seahawks at their 14-, 4- and 6-yard lines. He finished the game averaging 42.5 yards on four punts, but that number was not indicative of his impressive hangtime and control. Scifres has yet to be named to his first Pro Bowl, a statement that won't be true for much longer.
