The NFL may be headed for an uncapped season, but the Steelers are imposing their own salary cap. Pittsburgh plans to follow a self-imposed cap in 2010 and won't take advantage of the lack of a collective bargaining agreement to add more quality free agents than usual. "We will operate as we always have. We will operate as if we have a cap," director of football operations Kevin Colbert said Friday. "You don't know what you're going to be dealing with. First of all, no one's been in an uncapped year since 1993, so it's a whole different era and no one knows how this will play out. We don't know, if there is a new (labor) deal at any point, what the new rules are going to be."
