Like restricted free agents, we tried to keep tabs on the Kansas City Chiefs unrestricted free agents this offseason. These are the guys that A.) have four or more accrued seasons in the league and B.) have an expired contract.
The list of the Chiefs UFAs released by the league today matches up with what we had (if you include my late edit to add RB Jackie Battle as a UFA) except for one change -- WR Kevin Curtis isn't an UFA.
The Chiefs actually have the right of first refusal with Curtis, which basically means they have the right to match any offer he receives.
The Chiefs signed him at the tail end of the 2010 season and they didn't really know what they had with him coming off of an injury and all. So my guess is that Chiefs GM Scott Pioli wanted the right of first refusal clause in his contract so that he could retain him if necessary given all the uncertainty heading into this offseason.
So Curtis can go out and solicit offers from other teams but the Chiefs have the right to match anything he gets.
