The Kansas City Chiefs aren't announcing the status of their restricted players but we're whittling down the list of players via various media reports. The latest one is S Reshard Langford, who did receive a tender, Bob Gretz of BobGretz.com reports (FYI: That Bob Gretz link has some good stuff on the Chiefs scouts).
The period of making any transactions is over until a new labor deal is complete so these are moves the Chiefs apparently made before the deadline and the news is just now getting out.
Langford came into the league in 2009, which means he has two or less years of experience making him an exclusive rights free agents. Those players have no negotiating rights so his choices are to sign the Chiefs contract offer or don't sign and don't play.
So, as some have said, exclusive rights free agents are only free in the sense they're free to quit football.
Here's an update, via various media reports (mostly from Adam Teicher of the KC Star), on where we stand with all the players that were restricted in some fashion entering the offseason:
Franchise tag; LB Tamba Hali
Restricted/exclusive rights free agents tendered: CB Brandon Carr (1st), OT Barry Richardson (2nd), DE Wallace Gilberry (2nd) and Langford (ERFA).
Restricted free agents not tendered: FB Tim Castille, OT Ryan O'Callaghan, CB Maurice Leggett and RB Jackie Battle.
Signed: LB Cory Greenwood
We don't know: TE Leonard Pope, C Rudy Niswanger, QB Brodie Croyle, TE Brad Cottam, FB Mike Cox and LB Corey Mays.
