Really? The X-men should really be higher on Osborn's list. Because they are pretty an army of supers, an army with several of the most powerful beings on the planet on the team. The only thing that could make the team more powerful at this point is if Jean came back and brought all the other dead X-men with her.
And that huge team are all pissed at Osborn and his Avengers at the moment. And he's going out of his way to piss some of them off even more.
