What NFL coach could last 20 years in his current job?

According to Dan Patrick, two separate sources within the Falcons hinted to him privately that Mike Smith would have been fired if they lost their playoff game against the Seahawks. Yet he makes this stupid list right behind sean payton? Ridiculous. Payton survived the Vicodin scandal, he survived bounty-gate and even received a new contract after that. He has one of the most secure positions in the league.
