I think you are setting up some strawmen there. I think few have said he has to make the SB or bust next year. I think many that have said they think the Cowboys need a new direction is simply looking at making the playoffs and not spit the bit immediately like they have. Show some progression here, not the same old.
Also, to suggest we have had a SB potential team for the vast majority of Garrett's tenure is a total reach. To set the standard as Cleveland, is just setting a really low bar for Garrett and the Cowboys. I mean in that sense, if Garrett spits out another 9-7 season but doesn't make the playoffs, you can call that a win because.......... "well, hey, at least we aren't the Browns!"
And let's note, we aren't talking about a coach in his 3rd or 4th year here. Garrett is now in his 8th full season. So trying to mitigate the criticism to emotionalism or fickleness or impatience is just bull at this point. If Garrett fails to make the playoffs in 2018, how can anyone argue that fans that want a change are being too emotional or impatient? It makes zero sense.
First off, I'm not saying "hey, at least we're not the Browns." I'm saying that the team is going into the season knowing, or at least having exceptional confidence, they will be competitive for the playoffs. Simply drawing distinction with the fans of a team like Cleveland (although a case could be made they are closer this year than they have been is 15+ years).
Secondly, I've not said they were a SB favorite for any of Garrett's years, but with very limited exception, it could not be said they didn't have a chance to go. Again, the first criteria is to be competitive for the playoffs. There's not a non-playoff team that has ever won the SB. And you don't have to be 14-2 or 13-3 to win or play in the SB. The Giants were 8-6 in 2007 before going on a 6 game streak to win.
There are indeed fans that have posted he should be fired if the team doesn't get to the SB. Maybe not the majority, but there a significant number have said play in an NFCC or else. I just don't subscribe to the thought that it's "this accomplishment or bust" other than to be competitive of which they have been for the vast majority of his time as HC. The major exception was 2015 of which he and the rest of the coaching and front office staff failed miserably. I don't give him a pass for 2015, but neither would I fire him after that season. He and they responded in 2016 with as diametrically opposite a job as 2015.
If fans are simply rational and base their views on well thought out and analyzed positions, why are there so many comments like "Clapping Carrot"?
I've said it before and I'll say it again, there was significant voicing after the 64 season that Landry should be fired. There wasn't talk radio, or social media, so it was simply water-cooler talk and newspaper/print media. Clint responded with a 10-year contract for Landry and the rest, as we say, is history. I'm not suggesting Garrett is or will be the next Landry, but the point is that Clint saw what the fans and media didn't and made an informed, intelligent decision.
Finally, I'll have no problem if Garrett is fired IF the team is not competitive and stops listening to him or buying what he's selling. There's no evidence of either in my opinion, self-serving TO aside.
