In my mind the biggest question mark on the Kansas City Chiefs free agents is DT Shaun Smith. Will he return as a Chief?

Apparently, it's a possibility.

The KC Star's Adam Teicher reported that, after the Chiefs agreed to terms with C Casey Wiegmann, WR Terreance Copper and CB Travis Daniels, they were also working on an agreement with Smith.

It may not get done but this tells us that the Chiefs would like him back in some capacity. Great news, if you ask me, considering Smith is arguably the best defensive lineman on the roster and he also helps give this defense some personality. Let's hope they get it done.

Teicher also reports the Chiefs are working on an agreement with S Jon McGraw.

Here are the remaining unrestricted free agents for the Chiefs: NT Ron Edwards, DE Shaun Smith, S Jon McGraw, LB Charlie Anderson, RB Jackie Battle, FB Tim Castille, OT Ryan O'Callaghan, LB Corey Mays, TE Leonard Pope, C Rudy Niswanger and QB Brodie Croyle.
