Well, the free agency negotiating window starts in 3 days and the Vikings only have $5,340,897 in cap space. I guess they are waiting until the last minute to release or restructure players. It would be a classy move if they released players before the window opens so they can get out there early.
Kind of hard to do a mock draft without speculating on what moves they might make. I think they can go in a number of directions. Release several players creating a lot of cap space and then hitting free agency as hard as they can or restructuring (not pay cuts just converting salary to signing bonuses) and not doing much in free agency.
