I absolutely hate the concept of “you don’t have another QB, so you have to sign your guy”.
Its a stupid concept that has been proven, over and over again, to be an awful way to evaluate and make decisions.
You sign Lamar if you think he’s an elite guy that can carry you to win a SB. If you don’t believe that, you don’t pay him elite money. Elite money deals for good to very good players never work out.
