"Especially with Antonio Gates, Malcom Floyd and Legedu Naanee sidelined, seeing Vincent Jackson on the practice field drives home just how far the Chargers' receivers' corps has fallen.

Just in the 20-minute individual period, with him running routes against air, Jackson made a half-dozen moves/catches that no other presently healthy Chargers receiver could. And he made it look easy.

Unfortunately for the Chargers, he won't be available to help them the next two games while he serves his time on the Roster Exempt List. (Don't hold this particular fact against A.J. Smith. Jackson almost certainly would not be here yet if he weren't forced to by being on the Roster Exempt List.)

But Jackson will likely act as Houston Texans receiver Andre Johnson the rest of practice, giving the Chargers defense a rare opportunity to go against a scout team player who is arguably as good as the real thing."
