This is just a theory of mine. But the PIS thread got me thinking. Do writers not understand the vast power level difference when we see Cap hurt Hulk or to the point when Cap knocks out the Hulk. But what's strange is that it's not just the Hulk as other writers have done this with other times or other times Steve hurting foes he has no business in doing so. But I've always had a theory that Steve's mind or sheer will can produce his abilities or power level to do what is required.
This isn't about the argument that Steve is peak human, nor an argument that Steve is a certain level of Super human. This is more a theory that Steve is at a certain particular level and that level he exceeds by a great degree, through the sheer will of his entire being. Some examples of this that caught my eye that sort of display this type of feats. This is a oldie from vol 1, notice how Steve does this super jump as stated with super human strength. I know the jump doesn't look like much but back then it was to high for Falcon or Sharon. As it concludes the adrenal strength of grim determination.
Other feats show case his ability to do what he wants, notice how Nick Fury questioned Steve on being able to throw his shield at a in flight ICBM. And why shouldn't he? A ICBM travels about 13-15,000 mph.
Nick Fury: Fer crying out loud you can't possibly think that....that....(as he sees the shield get closer and then much closer to it)
Nick Fury: I must have forgotten who I was talking too. When Captain America says he's gonna get something done. He get's it done.
An entire skyscraper falls on them( skyscrapers vary in weight but some can weight up to 40,000 tons or much more). There only hope Cap uses the impact absorbing shield. That scan makes it clear that it can only take so much of that weight. It absorbs force/impact but it doesn't make that weight magically "disappear". This is a momentous feat for sure. As it states the rest of the weight is being held up by the mightiest will on the planet.
Cap believes in the dream so much, he defeats Nightmare who is God in his realm.
