Eventually a new CBA will be reached, and if the plan currently being hashed out by owners in Illinois ultimately comes to fruition, that CBA (per Adam Schefter) will include a provision granting unrestricted free agency to players with four years of NFL service.
Several Vikings players who were RFA under the now-expired CBA would become unrestricted under the new agreement, including Sidney Rice and Ray Edwards. 4-year players tendered as RFAs under the old CBA would have their tenders wiped out, allowing them to negotiate freely with teams.
Sidney Rice, for his part, has made it clear that he intends testing the market when and if he becomes a free agent. Tom Pelissero has tweeted that he believes Rice will have a hard time finding a team willing to sign him to the large long-term deal he wants, strengthening the possibility of the Vikings re-signing him to an incentive-laden contract.
Ray Edwards would also become an unrestricted free agent under the new plan, and given Edwards’ recent comments, it seems 100% certain that he would leave.
Chris Mortensen of ESPN offers this longer rundown of some of the financial details currently being hammered out by owners. As expected, the new plan would provide for a higher salary floor, forcing teams to spend more of their revenue on players and opening up the possibility of an insane free agency period as teams scramble to reach that minimum (a scenario outlined in more depth by TVA’s Jon Merkle).
