I'm guessing TCU's legal fees have already gone over 200k, and would've wound up north of 500k if this actually went to trial. This leads me to believe his settlement is somewhere near or below 300k. Since it was likely a contingency, up to 40% is going to his attorney. After taxes, I think his ceiling on take home is 133k (but probably lower).
This is nowhere near retirement money. KL would've been much better off keeping the goodwill he built during his TCU career with our alumni, than having that settlement. He could've milked a 50k a year job off of some TCU alumni sap for the next decade at least. That ship has sailed.
This is what happens when you get caught playing checkers instead of chess.
