I heard them mention this in passing on the radio today, but they also mentioned that they have to not only sign their own free agents, but their draft class as well. I'm not sure how much that would cost, but it sounds like they'd be wanting to sign a dozen guys before they even looked outward. i've seen it broken down where they could afford to give some nice money out at positions of need (including a huge contract to sidney rice), sign their free agents and draft class, and have a bit of money left over.
