There is so much wrong with this "analysis" I don't even know where to begin. I guess I'll start at the top.
1. The Cardinals aren't dealing Rosen. We don't have a 1st to offer this year anyway. What did he show you that suggests he's better than Dak? Oh right, nothing. I have a theory about this I'm keeping to myself, that I hope is wrong about why anyone right now would prefer Rosen over Dak. If Rosen was the QB on this team, they'd win 6 games. Maybe 8, tops. If Dak got injured this year, this team would be 4-12. Maybe worse. There's no chance they would have beaten New Orleans, Philly twice, Seattle, or scored even 10 points against the Rams last week without him.
2. Get off the bandwagon now. I won't stop you. I think this team is much closer to New Orleans than they are to New York as far as the NFC pecking order is concerned. A good draft and a couple key FA additions and they'll be in the running. That's all you can ask for.
3. The roster errors made during Romo's heyday aren't being made any longer. This team is much more cap conscious and won't let themselves get hamstrung by big contracts.
4. How can you say with any certainty that this defense be wasted? Every starter except Lawrence is on a rookie deal. Jones and Smith will be getting extended fairly soon. Crawford will be released this offseason, I think. Lee is going to retire as well. All the rest are on very affordable deals. This defense has a good 3-4 year run in it, with how NFL windows average out. Let's check it once it's hit its expiration date before we decide it's been "wasted."
5. Dak started for 2.5 years at Mississippi State in a college spread offense but don't let facts get in the way of a good narrative. The offense he runs in Dallas is among the most complex. Not that that's a good thing, but that's just how it is. He has a lot on his plate for a guy who's been doing it for 3 years now, basically learning pro-style QB as opposed to the spread he had in college. This is the offense Romo was running after 5+ years of playing QB. Dak got it as a rookie.
6. He doesn't have the talent of a 1st round guy. No one says he does. I'm certainly not saying he's perfect. He has some mechanical stuff to work on. But he has consistently improved every year and I see nothing to suggest he won't continue to do so.
But to act like the guy is a complete scrub when he's carried this offense in every playoff game he's been in is idiotic. Zeke ran for 45 yards, the defense got shredded, the team loses by 8 points and you're out here acting like he blew the game. That's just bull **** in my opinion.
IDK what it is. You've got an axe to grind with him because he's not Rodgers/Brady/Manning/Aikman. Maybe you're just one of those "grass is always greener" types.
Every QB made a bunch of poo throws this weekend, including a bunch of future HOFers. Demanding perfection from Dak, or any QB is just setting yourself up for disappointment. His playoff numbers exceed Romo's in every category that you could consider.
7. Downfield aggression is product of offense design. But this is obviously Dak's own playbook, so it's his fault.
Dallas didn't have a legitimate deep threat with Dak at QB until they acquired Amari Cooper. Unless you're out here saying they should have been throwing bombs to guys like post-foot injury Dez Bryant, Terrance Williams, Brice Butler, Deonte Thompson, or Cole Beasley all this time, I don't know what else to make of this other than you're making up another reason to blame Dak.
I've said this a thousand times. Scott Linehan is the biggest problem, and the easiest one to fix. Getting a guy who will fully utilize Dak's skill set would be a nice change. Getting a guy who will call plays to keep the D&D manageable will also be nice. Take a deep breath. This team is very close.
