Shit, I wouldn't pay Jones until you see how he fares in a 4-3...and how Saunders looks.
This is a different scheme...and KC has a ton of players on a 1 year or final year deals...including their their 2 starting CBs. They set it up to keep the players that fit.
They'll get a 1st round pick for Jones...if they decide to trade him after this SB year.
