After spending most of 2009 as a healthy scratch, Davis was thrust back into the rotation last year when injuries decimated San Diego's receiving corps. He fought through a painful rib injury to average three catches per game over the first seven contests before succumbing to a season-ending groin injury.
It was the second time in three years a groin injury sent Davis to injured-reserve.
It would be foolish to depend on Davis going forward, but the same could be said of Sanders. The Chargers deemed Sanders' signing a low-risk, high-reward deal after inking him to a one-year contract. The same description applies to Davis, who enters the final year of his rookie contract with a salary of $840,000.

But the risk is also lower with Davis, who would be asked to be a situational player rather than an every-down contributor. The Chargers will likely need receiver depth, too, as Malcom Floyd, Legedu Naanee and Kelley Washington all figure to hit to open market. The Chargers neglected to tender Naanee in the event he becomes a restricted free agent, signaling he is no longer in the team's plans.
If Floyd re-signs and Vincent Jackson accepts his franchise tender, San Diego's depth chart could feature Jackson, Floyd, Patrick Crayton, Davis and Seyi Ajirotutu. That's a dynamic combination of experience and upside.
In that scenario, a healthy Davis still has a small place in the rotation and can step in if one of the top-three goes down. He can also help out as a punt returner, which may be key with Darren Sproles ready to leave as a free agent. Antoine Cason and Crayton can also return punts, but Norv Turner would prefer not to expose them to the extra hits.
If Davis is hurt, on offense or special teams, there is still plenty of talent to keep the machine running on all cylinders.
So, why keep a player when there is no dispute the team can survive without him? The same reason the Chargers added Bob Sanders: the reward warrants the risk.
Should the Chargers give Davis another chance? Discuss in the message boards.
