It appears fans will have to monitor the Collective Bargaining Agreement next year, assuming the owners and NFLPA can reach an agreement, for how UFA and RFA are handled. Because of the uncapped year in 2010, rule changes won't allow for restructuring of contracts for specific groups of players.
Williams and Kalil are among a group of the league's best young players in a contract limbo, forced to wait on lucrative new deals because of the "30 percent rule," which sets restrictive guidelines for renegotiating existing contracts - and could ultimately cause the Panthers to lose Kalil without compensation.

If the new CBA is like the now defunct CBA, Williams could be secured with a franchise tag while a new contract is negotiated, but for Kalil, there appears to be no protection. If he becomes a UFA, he could be gone with the Panthers not even getting any compensation.
It will be interesting to see how this all plays out, but losing any player because of the CBA running out this year shouldn't be allowed to happen.
