Ravens hoping for balance

Editor's note: These grades were assigned by the individual correspondent and not by Pro Football Weekly.

Upgrading their longtime struggling passing attack was the Ravens' priority of the offseason.The Ravens hired Jim Fassel as offensive coordinator, signed WR Derrick Mason on the first day of free agency and drafted WR Mark Clayton with their first pick in the draft.

These additions remove all excuses for QB Kyle Boller. The third-year starter has a proven play-caller in Fassel, a legitimate wideout in Mason and a breakaway threat in Clayton. With defenses determined to stop the run, Boller must make them respect the pass. His development will determine how far the Ravens go.
