The Giants did not accumulate talent though. Just to illustrate my point is there a single position group where you would say the Giants are better than the Ravens? I am not even sure I would say they are better at WR and they spent a lot of money on JAGs.
The fact that they are bricking on the draft means that it does not matter whether they had a QB or not right now. If Jones was Lamar they would have no reason to sign him because they have no parts around him and nothing that suggests they will be good in the next 5 years. So yes if you miss on every pick you are going to be bad no matter what scenario you pick, also known as pulling a Raiders/Lions.
All the Giants have shown is that you need the underlying pieces to be good. If Daniel Jones was good it would not matter because they would never catch up to the rest of the NFL having to largely sit out free agency because they signed their QB. So basically they would have a QB and not be competitive because they would be competing and losing to teams that have deeper rosters because they have a QB on a rookie so they can use all 3 aspects of roster building.
Edit: Basically because you seem to be getting confused (though your tendency to strawman also does not help) the makeup of a Super Bowl team is fairly universal. Get a SB level QB (of which there are about 18-19 in the NFL right now) which means decent but obviously not Pro Bowl level and then surround them with as much talent as possible. The only ways to do that are the draft, free agency, and trades. If you are spending 40-50m on a QB that means 2 less elite players in free agency so if you need to surround your QB with elite talent you now have 2 less than everyone else so you need to somehow make that up in the draft. Alternatively if you trade the QB you are no longer down 2 potential elite signings but you need to find an adequate one in the draft but you also have more picks than everyone else.
1. I know the Giants didn't acquire talent. Because your model can't guarantee that. All your model does is give them potential draft picks and money to spend. What happens if they don't draft well? What happens if they don't spend the money well?
The Giants is what happens. That's what happens when they do what you want them to do, but they don't execute it. Your entire argument is "I get two elite players at that price". Well, the Giants paid that same price tag, except they didn't get two elite players. They got players who just got paid a lot and didn't produce.
Hence, why the model sucks. The model requires the same thing that paying a high end QB does... quality drafting, quality FA signings.
2. Correct, it means you have less money to spend. And it means you need to do better in the draft. I'd rather be in that category, then being in the category of thinking I draft a mid-tier QB, turning out I didn't, and then it doesn't really matter what else I do.
3. Last year the Rams spent over $45M on the QB room, including nearly $25M for a QB that wasn't there. Did it seem like they struggled to get elite players there? Nope, they didn't. They also drafted well.
Imagine that. Teams that have a very good (or better) QB and draft well seem to perform well every year. This ain't rocket science.
