Sounds like the Bills are still up the cap.
Bills Under Cash To Cap Figure: The Buffalo News did a nice job of breaking down the Bills money situation for this year. Despite the lavish spending on day one of free agency on three offensive linemen, the Bills remain just below the salary cap figure in real dollars. The league raised the cap to $112 Million, which means the Bills would spend that much in real dollars this year. The News figures the team has spend $103 Million, that leaves them $9 Million in real dollars to spend but at least $5 Million will be used on rookies. The team could free up more space by releasing players, Takeo Spikes continues to get mentioned. The team is well below the cap as they are about $17 Million under, so if they wish they can break their rule and still be under the cap.
