To play Devil's Advocate for a moment, at least in early NEW AVENGERS issues, Bendis was willing to have the heroes do things like that. Spider-Man offered advice on the Savage Land, since he had been there. He also offered advice on Electro before, despite once taking on the Hulk solo in REVENGE OF THE SINISTER SIX, Luke Cage made him pass out with a sneer. So it isn't outside the realm of possibility that whatever Avengers/heroes who plan to confront Osborn could at least give Spider-Man the floor for advice. After all, every time Dr. Doom does something, Mr. Fantastic (if not the entire Fantastic Four) are usually consulted. Such moments in NEW AVENGERS for Spidey, though, were few and far between; more often
Spidey was almost the Rick Jones of the group, seeming in awe of every situation. I haven't actually read the title in a year, but Bendis as a writer seems to see himself as a crocodile; never needing to evolve.
Of course, on the other hand I could imagine someone claiming that "it doesn't count back when he was throwing pumpkin bombs from a man-purse" since Osborn's power class is very different in his Iron Patriot armor. Bendis is after all a guy who dismissed the Scorpion as "someone who throws his ass at you".
I still see Spider-Man's odds of getting the final take-down of Osborn here as extremely slim at best, at least based on prior Bendis works. Based on his prior works, though, the odds are slightly better that Spidey could at least be consulted. But I don't see him taking Osborn down. We'll be lucky if it isn't another villain.
Such as while Luke Cage is cool and I do like that he's now a B-Lister, at heart he's only a mid-level tanker hero and villains really shouldn't be pissing themselves over him if they fought anyone over Class 45 or so, nor should he be written to seem to have more experience than Spider-Man. If anything, Spider-Man is one of few major Marvel heroes who began his career as a teenager and grew into it over a decade. But I digress.
It seems "everyman" is often confused with "immature/incompetent".
