I agree with most what you said. I think the containing a

ile QB can be fixed (hopefully).
I even agree with the part I bolded in your post.
But here is also the reality of the day. We should NOT have gone for it on 4th & 2 that ended up giving them a short field. That is a management mistake that has happened the last 2 years. We have the long snapper and punter that can pin teams deep now.
Then because of them deciding to go for it. It showed DR still has trouble finding open receivers in particularly important spots of the game. Similar to ILL and whatever other games last year. There were 2 wide open receivers for that first down he missed. I thought this is where he would take a step forward this year. But we'll see since this was only game 1.
Those 2 decisions ended up letting them back into the game. So, maybe this needed to happen in hindsight to allow the team to mentally figure out how to win a game like this.
