Please. Let's not act like anyone in the NFL business, or any business in general, aren't aware that this is how things work out.
Someone was getting fired. **** either runs down hill or someone falls on the sword. Even if Rex had the balls to fall on the sword now, Roman was gone once the session ended and the new coach was hired.
Any new coaches or coordinates know how the business game is played. Terry's money is still green enough to attract new personnel.
