You're right dominant is subjective. The Packers seem to be one of the top 6 best teams in the NFL currently. The only teams they lost to were all in the divisional round of the playoffs (I think? Just going off memory). That to me is a dominate team. Especially when you're beating teams that good. Teams that regularly compete for the superbowl (unlike any team McCarthy has coached for the last 7 years).
And I'm not taking Rodgers side. But I'm not going to ignore an entire group of complaints of MM's coaching ability that came from front office officials and other players anonymously. That's way to much smoke for there to be no fire. Rodgers is a nut case. But I find it hard to believe he had enough control in the front office and the locker room to form an MM lynch mob when Lafleur quite literally just waltzed in the front office one day and had Rodgers moving on. This is the Packers, who have quite literally been one of the best running franchises for a few decades now. Unlike the Jets, where Rodgers did get his way, but let's not act like the Jets have been anything remotely close to well run in the last 20+ years.
