Not all failures are created equal in the NFL. Fans of the Carolina Panthers are acutely aware of this after watching two separate regimes fall in a three year period. Nobody is accusing Ron Rivera and Matt Rhule of having the same story. Plenty of coaches catch lightning in a bottle on their way to a top job in the NFL and plenty of them find that success shockingly hard to sustain. But there is also a history of coaches succeeding when given that all to rare second chance.
Pete Carroll of the Seattle Seahawks was once laughing stock Pete Carroll of the New England Patriots.
