The Chargers, to a degree, displayed their concern by bringing back veteran tight end Randy McMichael. He stepped in when Gates was down last year -- the Chargers are hopeful he's not required as much in 2011.

But that hinges on how much attention Gates' sore foot requires.

NFL Team Report - San Diego Chargers - NOTES, QUOTES

Wide receiver Vincent Jackson is looked upon as a diva by many in the game.
But the Pro Bowler who has had his scrapes with the team over contracts said he
noticed no ill will when he reported to camp. While he has frustrated the
Chargers with his actions off the field, Jackson is a solid clubhouse guy with a
great work ethic and the respect of his teammates.

"Honestly, when I came in it was a like reunion with your family," Jackson
said. Guys welcomed me (with) open arms."'

--The Chargers used their first-round pick on run-stopping defensive end
Corey Liuget to try and shore up the run defense. Although he's yet to sign and
considering he didn't have an offseason to learn, it's questionable if he'll be
a steady contributor. But the Chargers also chased away three of their best
run-stoppers: inside linebackers Stephen Cooper, Kevin Burnett and Brandon
Siler. That's a lot of experience and muscle heading out the door.

Instead, much will be asked of veteran Takeo Spikes, but also Donald Butler
and Jonas Mouton. Butler was hurt all of last year; Mouton is a rookie.
