The first depth chart is made by the Baltimore Ravens PR department. While not set in stone, it can give a general idea about which players are on the upwards trajectory.

Starting defense:
Wide Receiver
Mike Wallace starting is encouraging even though when considering the absentees, it is not a surprise. If the season started today, Wallace and Aiken would make a better tandem than any non-Steve Smith Sr. receiver used alongside Aiken last year. If rookie wide receiver Chris Moore is back sooner than later, the Ravens figure to be in good enough shape at wide receiver.
