This argument is dumb, if Rex was a hall of fame caliber coach he would have been able to pick talent better both in his assistants and his players. While Rex was here we all know the offense was mediocre at best, but the special teams was horrible as well. Even with the so called greatest special teams coach ever. I am sorry, but a good head coach, especially one that depends on the field position battle, more than his wife's toes should have more than no freaking clue about 2 thirds of a football team. It's shear ridiculousness defending him like he is the second coming of Vince freaking Lombardi. I am saying this as someone that likes Rex a lot.
Rex brought this on himself. He should have paid more attention to detail and less on his vaunted defense. At the very least he should have dispelled that belief and act like he gave a excrement about the other 2 thirds of a football team. Frankly, sometimes it appeared if he lost 3-0 he would be happy his team played great defense.
