If Dak was fully responsible for those 2 INTs, I would agree with you. Problem is those 2 INTs weren't totally on Dak. THAT is the difference and the reason why Dak should be kept. Fix what is truly the problem on offense, but I do wish Dak would agree to a discount.
But for me Dak's responsibility on those 2 INT's is that he made those throws BECAUSE OF THE PRESSURE OF THE SITUATION. Indeed, when we went 7-0 (even 14-0) we were still running the ball, the failures happened when we abandon the run.
......it's as if (well in imho) Dak, Coaching and whole roster know that our offensive failing is when we're forced to step up and cant rely on 'our style of play' and have to take risks (of which we're excellent, and are able to do in the Regular Season, where you get to play the lesser teams).
I agree on the discount part, especially as we need a Defense that can hold....the problem is that even in the two SF play-off defeats the Defense did step up (to a point), and yes there were problems.....but Dak still had 4 drives to win/tie those games.
For me there's causal link and it starts with Dak in those risk taking situations, which I dont think we can overcome even with an elite Defense.....especially as pretty much every SB winning run, at some point, requires the QB to perform the comeback heroic's.
.....Then again, if Dak took that discount i'm still probably in lol
