Comparing being an accountant to being a HC of an NFL team is just ridiculous. They are not in the same universe. McCarthy walked away from the table Jones wanted him back so failed is the wrong word
Again, McCarthy is the John Calipari of NFL HCs. You can bang the table and say, “he has a Super Bowl!”, or you can look at roster composition and see that he has had 6-8 Super Bowl rosters that fell into his lap, and he has 1.
Now you want to play make believe and pretend this thing can be jolted into being a contender.
