Same career records both coached all of fame QBs both have a ring. McCarthy rehabilitated Farve into all pro again and developed Rodgers into a superbowl winning mvp caliber player and gave Dak his best years and his teams are always in the mix.
Why is Payton over him?
To me, a lot of it comes down to clock management. I'd say McCarthy was one of the worst I've ever seen, at least for coaches that were hewd coaches for a long time.
Maybe I shouldn't have said significantly better, but I do think Payton is better. Has less to do with me thinking Payton is great and more to do with thinking McCarthy was not that good.

Payton be resurrecting dead organizations from the grave, in unheard of circumstances.
