Chargers rookie update
Posted by ESPN.com's Bill Williamson
I have extensively covered the strong play of San Diego's top two rookies, cornerback Antoine Cason and running back Jacob Hester. Both players have been standouts in training camp and in the preseason.
The Chargers only have three other draft picks. I want to give a quick rundown on these players halfway through the preseason.
Running back Marcus Thomas: The fifth-round pick from Texas-El Paso is a hard runner and he is giving his best effort. Still, the San Diego backfield is crowded and Thomas may have trouble making the roster. He could be practice squad material.
Cornerback DeJuan Tribble: The sixth-round pick from Boston College is talented and has big-play ability. But like Thomas, he is entering a crowded position and will have to fight to make the final roster.
Offensive tackle Corey Clark: The seventh-round pick from Texas A&M has earned praise from coach Norv Turner. He may be on the bubble but Clark has the look of a potentially good right tackle.
Also, the team likes fullback Mike Tolbert. The undrafted free agent from Coastal Carolina will likely make the 53-man roster.
