Dak hasn't shown that he's reached the next level in his QB progression. Early on, his mobility was a big asset to compensate for his lack/limitations of passing ability.
Now, he doesn't display that same zeal to use his running ability, mainly due to his hesitation from injuries and his seeming want to prove that he is a legitimate passer.
He is still a quality QB but he has yet to show he is a Force Multiplier as a QB. FM's elevate their team and overcome player limitations. He hasn't shown that ability and now we are stuck paying him as a top QB and we may not see him reach that FM level. I think the struggles by his Oline have taken a toll and he doesn't seem as confident and that affects his accuracy.
He seems to gain a lot of his stats during garbage time after the team has fallen behind by double digits. He teases a comeback but seems to come up short more times than not.
Dak has shown that he is a top 10 QB in this league. We can all argue about where he falls from 5-10. Personally I put him at 7.
But your angle just goes to show your looking at this the wrong way. Dak's play, like all QB's will be determined by the quality of the players around him.
Dak has shown if that you if you give him relative time to throw and some weapons, he can play elite football. He is not a guy like Mahomes or Rogers that is going to skirt around in the pocket, buy lots of time. He can throw on the run and get out of trouble, but he isnt elite. But give him a good Oline and can play elite.
Thats where I have him. So Dak's play will be determined by how well we fix the Oline. He has plenty of weapons. But like Mahomes or anyone else, if the QB doesnt have proper blocking, the offense will be inconsistent.
And certainly its difficult to overcome 8-10 penalties a game by the Oline. Again, fix the line.
And this isn't about "perfect around him". Its about give a QB, like any QB, what he needs to be successful.
Guroppolo beat Dak, then beat Rogers. Stafford beat Brady. All because they had better teams then the other guy around the QB.
This isnt rocket science.
