The Ravens started the season with 6 receivers on the opening day roster, and 3 are done for the season (Steve Smith, Campanaro, Waller) and another has yet to play a snap. This leaves Kamar Aiken and Marlon Brown, plus trade acquistion Chris Givens, and former practice squad call-ups Jeremy Butler and Jeremy Ross as the active wide receivers.
While Givens and Aiken have had their moments this year, Brown has been near invisible, Ross has been solid in a limited role, and Butler has not gotten a chance yet and is completely unproven.
