jerry did do one other VERY important thing, he wrote a million+ dollar check to pay Herschel to accept the trade and that wasnt easy for him at the time because he was stretched ridiculously thin financially plus Walker was probably the most marketable player on the roster so he deserves credit for making it happen
its just too damn bad that this, getting credit for hiring Jimmy (and doing the thing Schramm couldnt do when he wanted to hire Jimmy..fire Landry) and owning the Cowboys isnt enough to satisfy his fragile ego but alas, here we are 30+ years later and nothing has changed
