The Vikings cleared salary cap space by releasing safety Madieu Williams, restructuring wide receiver Bernard Berrian's contract and releasing left tackle Bryant McKinnie.

But even with those moves the Vikings remain second-to-last in the NFL when it comes to available cap room, according to Pro Football Talk. The Vikings are only $380,000 below the $120 million cap, putting them ahead of the St. Louis Rams ($270,000).

Those are the only teams that don't have available cap room in the millions. The Atlanta Falcons, who are $1.1 million below the cap, are third from last in the league.

Two big issues remain the cap hits of linebacker Chad Greenway ($10.1 million on a one-year franchise deal) and running back Adrian Peterson ($12.775 million in the final season of his rookie contract). That's why it makes sense for the Vikings to get one or both of those players extended as soon as possible.

It would keep the players' happy and create more salary cap room for 2011, just in case that is needed.
