Chargers' intelligence report

Here is San Diego's preview page:

1. Rivers is refreshed: This season ought to be easy for Philip Rivers. Last year, top receivers Vincent Jackson and Malcom Floyd and tight and Antonio Gates were on the field together for about a quarter of a game. Jackson held out much of the season. Floyd and Gates were hurt late in the season. By the end of the year, Rivers was throwing passes to street free agents. He threw to 17 different receivers. Yet Rivers managed to throw for a career-high 4,710 yards. Imagine what Rivers will do with a healthy receiving base.

2. The pass rush is on: KC Joyner, the Football Scientist, expects the Chargers to bring the heat this year. The Chargers had a very respectable 47 sacks last season. They have a chance for a lot more this season. Joyner said the Chargers' 2011 opponents allowed a combined 592 sacks last season. That total ranks as the seventh most in the league. Expect the Chargers to blitz often under aggressive new defensive coordinator Greg Manusky.

3. Tolbert will be a horse: Just because the Chargers plan to use second-year running back Ryan Mathews a lot, don't think sturdy tailback Mike Tolbert will be forgotten. The Chargers love this guy, and Mathews and Tolbert will both get a lot of carries. In fact, if Mathews' durability issues continue or if he is slow to develop, I could see Tolbert getting most of the carries. Coach Norv Turner completely trusts Tolbert and loves how hard he runs. Tolbert is a plus player in every facet of the Chargers' offense.

4. Liuget is legit: It's not often that the No. 1-ranked defense in the NFL adds a potentially dominant front-three player. That's exactly what the Chargers have done. They took Illinois defensive end Corey Liuget with the No. 18 pick. Liuget has been explosive, and he has been a playmaker in camp. He often gets into the offensive backfield. He is a humble player who is willing to learn. The Chargers can't wait to unleash him in their starting lineup, giving them a playmaker to pair next to standout nose tackle Antonio Garay.

5. Spikes and Sanders are on a mission: The Chargers added veteran safety Bob Sanders and veteran linebacker Takeo Spikes to their defense. For Sanders, it's a chance to show he can still be the player who won the NFL Defensive Player of the Year award in 2007. He has played a total of nine games in the past three seasons because of injury. He has been healthy this summer, and he looks like the old Sanders. This is Spikes' 14th NFL season. He has never been to the postseason. Spikes knows this year is his best chance, and his play this summer has been inspired.
