This might be a case of a receiver losing his job due to injury.
But in reality, even early in the season when Chambers was healthy, he wasn't getting alot of targets. He had a bunch of early TD's, but not many yards.
Jackson and Gates are the primary guys for Rivers, and now Floyd is stepping up and getting alot of looks as well.
Just too many guys. If you start Chambers, you're just hoping for a miracle right now. Just bench him for awhile and look somewhere else.
