Isnt the stare a part of his mental make-up that he cant perform under extreme pressure. There's very little that can be done to overcome those issues......O-Lines, Receivers, Running game, Run Defense (to give him time), Secondary for field position......spend on getting all of that and still he comes up short WITH THE BALL IN HIS HANDS.
It's like saying, if we had a PERFECT team, Dak would be a SB QB. The closest we've come is 2023, that wasnt good enough and even if Jerry was able/willing to get a team of that caliber (very unlikely in 3 years, from where we are)......Dak is still there and ISNT the same QB (on many fronts, inc health) as he was then.
