There's a sign in the Halas Hall hallway just outside the positional meeting rooms that reads: "Ability is important, but dependability is critical."
No Bears player exemplifies those words more than receiver Marc Mariani, an unheralded sixth-year receiver who is making the most of a rare opportunity to play on offense.
Primarily a return specialist since entering the NFL with the Tennessee Titans in 2010, Mariani has filled in admirably for the injured Eddie Royal, catching six passes for 68 yards over the last four games.
