I hate to tell you but we have a huge variety of fans in terms of ages on here...many that were in diapers or grade school in the mentioned example. To say that only "real fans" would have been fed up at that timing is limiting the classification to a certain age group. The reality is that many fans, of a variety of ages, are totally fed up and the continual cycle of win early in the season, fall apart late season, get bounced early in the playoffs.
The fact that they were 12-5 two years in a row doesn't take the nasty sting / taste away that so many are used to over and over and over again for decades. I understand what you are saying about 12-5 for back to years is good and i do not disagree that its a big step in the right direction, along with a road playoff win for the first time in 30 years and the first back to back playoff appearence in 17. However, this fan base has suffered for a long time and I am perfectly fine with fans saying their frustration has peaked becuase they are tired of just having regular season success and no playoff success.
The challenge has become, if you know that you are going to never have playoff success and only have regular season success, then it becomes a situation where the regular season games become less fun since you are already assured of the outcome - this is how so many of the frustrated fans (who have peaked) feel and it is totally understandable.
I think the very definition of success has changed. The importance of regular season wins has diminished in my opinion. There is now so much sport.. so many games etc etc.. that each individual win has less and less merit. The league is defined by championships, by winning when it matters.
We could go 12-5 for the next 8 seasons.. and if we get bounced in the first week/2nd week each of those 8 years.. then it will be another 8 years without success.
So I can agree that we 'broke' a lot of ground this year with winning on the road, back to back playoffs etc.. but ultimately we lost and lost badly yet again to SF. It highlighted the gulf that still exists between us and the top teams.
The Alex Smith comparisons are perfect imho.. Smith was replaced after leading a winning season.. because the chiefs recognised he wasn't going to take the next step. I think Smith could have led them to many more 'winning seasons' but probably not further. We are seeing the same with Dak. Dak will win a lot of games with this offence and this defence. But when the heat is applied and the pressure is on.. he has now failed consistently.
The sting this season is they way we failed against SF. We watched a rookie QB beat us. We watched Dak turn the ball over in situations that were non-negotiable "play safe" situations. I think it has shaken some people who were Dak fans.. it showed a lack of growth, a lack of maturity, a lack of talent and was almost an 'unforgiveable' type game for some. I think that explains the level of angst with Dak being ramped up even more this year.
There is nowhere for Dak to hide after that SF game.. it wasn't the receivers.. it wasn't the defence.. it wasn't a lack of weapons.. it wasn't the coaching.. it was 100% on Dak that we lost that game. Also I think for a lot of fans we are now feeling like if we can't win with this squad.. then when? If we can't win with Dak, pollard, CeeDee, Zeke, Smith, Smith, Lawrence, Parsons, Diggs, LVE etc etc etc.. then when can we win? It is a scary question.
