Not many will answer your question.. probably because you lead with 'dak haters'.. which is just another overused insult purposed designed to cause argument.
There may be a few posters who truly 'hate' Dak.. but not many. There is a big difference between believing he shouldn't be our QB and hating the guy.
I also don't see many arguments that he is a terrible QB.. and I don't think he is terrible. I think anyone calling him terrible has either just watched the SF game again or likes to talk in extremes.
I believe that in reality, Dak is probably a very good human being, a great leader and a slightly above average QB on the field. That is actually a pretty good package. That combo will see him consistently ranked around that 12th-16th best in the league. That is nothing to sneeze at.. and a big reason why we have been 'around the mark' for most of Daks tenure.
The point of difference/real issue/pressing trouble is that we are now paying him elite/Top 2 money - which is WAY WAY OVER his value. Even his greatest fan has to admit that he has not lived up to his contract. At no point could you legitimately put him as a top 3 QB in the league.. no way, not even his greatest fan could say that with a straight face.. which means he is, categorically, getting overpaid.
The 'marginal' issue.. and the one that causes most debate is whether a guy that 12th-16th best (irrespective of how much we are paying him and what is around him) could ever be good enough to get the job done. Most of the angst and debate is about what we need to put around Dak to get success. How can you 'nurse' a 12th ranked QB to a SB? How many weapons do you need to give him? What coaches could help scheme him to success? What has to go right?
For me, to answer your question, Dak isn't terrible.. he is just nowhere near good enough to justify his contract and his contract means that we can't have enough talent around him to overcome his shortcomings.. and I believe he has too many weaknesses to ever be good enough to win anything serious. I don't hate the guy.. but I do believe that we need to move on from him ASAP because he is not good enough to win.
The one thing I will add , is every qb or offense needs good coaching , playbook, game mgmt, game plans.
Without those being good it is hard to be good, and this is what dallas has lacked since 2007.
Dallas should have beaten the giants in 2007 but they had inferior coaches, wade garrett etc. That cost them a shot at a SB run.
Same thing for 2014,2016,2021,2022.
Coaches make a difference, and jerry wont hire a good HC , tries to create a OC in kellen, tried to create a HC with garrett, and he
hires Mike, cause he heard bells, and he says he wants mike here a long time lol.
I dont think mike is a good HC, he is avg, typical nfl HC. Him getting cowboys to a SB is unlikely, and winning one is even more unlikely.
I read here all the time how many weapons does dak need? lol, but how many does Mike need??
It all starts and ends with coaching, not the QB.
And I am not a fan of dak, but no qb can be good consistently, or in big games, with bad coaches.
