Philip Rivers stood in the parking lot at Chargers Park this week a teammate rolling past in an SUV as the quarterback searched for a way to encapsulate Vincent Brown.

It's not just one attribute. Brown has another. There aren't just those two. There are these.

About five seconds passed.

“I'm trying to think of how to describe him” Rivers said and then he found it. “He's everything you'd want in a wide receiver.”

On Thursday night the Chargers will play their second preseason game facing the Bears on the road. Of greater significance Brown is expected to start in his first game action since suffering a broken ankle against the Cowboys last August coincidentally in the second exhibition of that year.

“I'm excited to get back out there and see what I can do” Brown 24 said.

That affirms one of Rivers' descriptors for Brown: He is humble.

Deep down Brown certainly knows what he can do just as Rivers the coaching staff and other Chargers teammates do. They've seen it on the practice field and during limited game action since his selection in the 2011 third round. Because of injuries Brown has yet to consistently showcase what the Chargers have seen in private and that process can begin Thursday.

“He runs great great routes he's strong to the ball he has huge hands he has range and he's a guy you trust” Rivers said. “I know he's anxious to play. He probably feels like it's taken forever to get his career started and in a lot of ways it feels that way.

“We always talk about 'Vincent Brown Vincent Brown.' The guys know him how good he is. You'd think he's played for four or five years but he really hasn't.”

Brown is still beginning.

He entered the league during its lockout so there were no organized team activities and there was no minicamp. The first passes Rivers threw to the former San Diego State standout came at local schools in casual player-organized workouts. Quickly Rivers liked him.

Brown would start four games as a rookie. He was raw understandably between the lockout and a hamstring injury in training camp but the ability was there with 13 catches 234 yards and a touchdown in those starts.

Brown gained a better grasp of the playbook last year had an impressive spring and was one of the NFL's most productive receivers in the preseason before being tackled from behind Aug. 18 following an 18-yard touchdown catch.
