After the 2015 season finishes, there are four prominent members of the Kansas City Chiefs defense that are unrestricted free agents. Sean Smith, Derrick Johnson, Eric Berry, and Tamba Hali all have contracts that expire this offseason, and all have played a huge part in the Chiefs success over the past few seasons. So which one of the four do you keep if you can only keep one?
Derrick Johnson
Johnson has been absolutely great as a Chief. From the day he was drafted he came in and was a huge part of every defense he was on.
