Khalil Mack's deal dubbed Bears' worst by Bleacher Report. Considering his productivity and how much better he makes others, this is probably the best contract. Not only does he produce and help others produce, but the money in his contract has been converted to bonuses so they could free up cash and keep or sign other players. Not even close here Bleacher Report. Trey Burton's and Adam Shaheen's money are the worst considering they get nothing in return.
