Wide receiver Chris Chambers, the Dolphins' No. 1 pass-catcher, is reportedly on the trading block, a move that could signal the growing confidence in the development of first-round draft pick Ted Ginn Jr. as a wide receiver. Although Chambers has not been prominently featured during the preseason, it is not believed to be because of any level of disappointment from the coaching staff. But the NFL Network reported that Chambers' name has been popping up in league circles, and teams are aware that he's available.
