Granted it's been several years now, but I don't remember a ton of people being upset by the Dak pick at the time....maybe i'm wrong? Dak's rookie year he was a bus driver who showed flashes of more. He had a really good offense around him that worked well with Dak playing within the system and finding the open receiver.
Dak didn't really have too much of an issue until the team asked him to do more and more, and I think that is the issue MOST of the "Dak haters" have. There are some true Dak haters around here who dislike the guy simply because he forced Romo into retirement and wasnt their guy, but I think most are pretty level headed and acknowledge that Dak is a good QB, but struggles to be that guy who can pick his team up and put them on his back against stronger competition.
If the Cowboys still had that 2016 Oline and would actually stick to a run-first approach Dak is probably not injured right now, and thriving. Reality is though you can't pay your QB top money, RB top money, WR top money and still keep your Oline a top unit. Especially now with Cooper gone, Collins gone, and resources going to build up the defense more so than continuing to build up an offensive powerhouse Dak hasn't produced to the level of play where you look at him as a super bowl caliber QB. We see constantly that it becomes very difficult for QBs to make it to Super bowls after they take on that big pay day. Brady has taken less money and won several. Mahomes made two super bowls on a rookie deal, now we are seeing him lose his top weapon in Hill. Rodgers is a first ballot hall of fame player, but cant make it back and has looked pretty average so far without an elite receiver.
I don't have an issue with Dak, he's a player you can win with. I do have an issue with the contract Jerry signed him to. It's a handicap for a team that has already made several other poor decisions with the Zeke deal, Jaylon Smith deal, etc. With guys we need to start thinking about resigning the next couple years in Diggs, Parsons, maybe even a Lamb I think you need to be open minded to other solutions if Dak wants to reset the QB market after his current deal is up. I'm all for Dak leading this team, but does Dak at $40MM give you more of a chance to win vs a Marcus Mariota at $8MM? Depends on if Jerry/Stephen actually spend the money and do it well which is another thread that can go on for days and days.
