I think it depends on what you want the team you root for to accomplish - The Packers have been great at being pretty good for a very long time, going on a magical Super Bowl run as a 6 seed once....then they largely underperformed preseason expectations under McCarthy in the postseason until that nucleus got old along with a mix of bad defenses and atrocious special teams, and he got fired.
MLF's hiring came with an infusion of free agency and a few good drafts to bolster a defense and saw a Rodgers resurgence, then they couldn't win home playoff games to get to the Super Bowl when they were expected to do so. Since then, they've been in perpetual 7 seed mode - injuries did derail them from having a higher seed and more realistic chance at a Super Bowl run this season, but they still should have at least made the divisional round. With the current roster, I just don't feel like the Packers are on the upswing with the same head coach. They still have consistently awful special teams that cost them games, and their defense has been inconsistent at best with alot less quality depth than what all the draft/free agency capital used to build it should. Some of that is Gute, but player development by the coaching staff is also important.
Fact is that McDermott got fired because the NFL still can't figure out what a catch is, and MLF got an extension despite his teams repeatedly showing they can't close at crunch time in the playoffs - that has spanned multiple starting quarterbacks more than good enough to win in the postseason and typical NFL roster and coaching staff churn. The only common denominator is MLF. I don't like the fact he's still the Packers' head coach.
