[ Game of Thrones/ ASOIAF ] Who would've become king after the Rebellion if Robert had died due his injuries sustained at the Trident?

Did Robert become king because of the smidgen of Targaryen blood in him? Or was it mostly his stance as leader of the Rebellion against the Crown? So would Stannis have become king as Bobby B's younger brother or would some other leader of the Rebellion like Jon Arryn or Ned Stark ascend to the Iron Throne?

There's a real chance that it would have been Ned Stark. Not because he in any way wanted it, but because Jon Arryn would have offered it to him and he would have thought he had a duty to clean up the mess he'd helped make.

It depends on Stannis, though. If Robert hadn't been crowned, would Stannis think that being the usurper's brother made him the rightful king? If so, Ned would step aside gladly; if not, Stannis would probably no more want the throne than Ned would, and Ned, being older and with more experience of leadership, might be seen as a better option.
