According to profootballtalk, the Redskins are still $11.9 million under the cap. That begs the question, of what, if anything, they should do with that money. Obviously, they have to keep some available for injury replacements, but at most $2 million should cover the pro-rated minimums for several replacement players over the remainder of the season. There are several starters in the last year of their contracts who could be extended. I would be all for this, if they sign for reasonable amounts. Especially Fred Davis should be a priority. Given that they are this far into the season and there isn't much discussion publicly of any extensions, and the players are now only a few games from unrestricted free agency, I don't think we'll see much happen with extensions.
So what do to with all that cap space? Trent Williams is due $11 million for next season, far and away the largest on the team. I'd restructure his contract to pay him a roster bonus of $10 million during this season and reduce his pay to $1 million for next year. This keeps Williams total pay the same, and moves $10 million in cap space into next season. That's more than enough to sign next years Albert Haynesworth! Get to it, Allen!
