Redskins, Cowboys could go “nuclear” over cap mess

[KI Skins Fan]

I have a couple of questions for those of you who keep track of and understand the workings of the NFL salary cap.

I have read specualtion that the Skins haven't been able to re-sign London Fletcher because they lack the cap space to do so. Is that true?

If the Skins lose in arbitration or if the arbitration drags out would the Skins be put in a position to cut players or could they realistically make cap space for Fletcher and other players by restructuring contracts?

Would it be necessary for the Skins to trade or cut D. Hall, whose contract counts by far the most against the cap, in order to sign Fletcher?

Any knowledgable answers would be appreciated.
