So I'll be the first to admit, I know nothing of player contracts or anything.

What does RFA?

Same with UFA?


also while I am at it, I was on NFL.com and saw these guys were declared FA's. Does that mean the Chiefs don't want to resign or they are negotiating?

Jon McGraw declared free agent.
Rocky Boiman declared free agent.
Pat Thomas declared free agent.
Jason Babin declared free agent.
Oliver Celestin declared free agent.
Adrian Jones declared free agent.
