That goes back to Orys, who even if not The Conqueror's bastard half-brother, is still the very first Hand of the King, and how the office got its name.
Indeed, for all Robert's problems, he at least initially seemed reasonably popular (for people not named Cersei or surnamed Targaryen, Martell and Greyjoy, anyway). He was never deposed, and only faced one serious rebellion in his entire reign (unless you count the Stark-Lannister feud afterwards). He was diplomatic and generous (helping bankrupt the realm, but that's for the future), but he also had some legitimacy. If Aerys and his descendants were attainted, then Robert would be the closest living relative in the Targaryen line. That counts for a lot to smooth a transition (as Renly would have found out if he had taken the throne). Royal blood may be an illusion, but people believe in it, which makes it something real, as Varys would probably say. Don't mistake Renly's self-serving speech (where he emphasizes Robert's claim as conqueror in order to denigrate his claim of blood) as cold fact, rather than Renly's attempt to justify his own blatant power-grab.It'd be pretty hard to rule peacefully as Stark on the iron throne. The smallfolk doesn't really like followers of the old gods, and about 80-90% of the realms people are followers of the seven.
Long winter -> pagans are quilty
bad harvest -> pagans are guilty

The Starks (even if they have somehow have Targ blood which has conveniently never been mentioned, even when there are plenty of instances it would have made sense to bring up if it existed) would have a much more distant connection, at which point you might as well throw in the Blackfyres and Aeron Brightflame's kids and the Martells and everyone else with a drop of Targ blood. It would be a recipe for another civil war, as both Tywin (who also had a chance to try to forcefully seize the throne, at least in Pycelle's opinion) and Ned both realized.
From what I understood Robert was actually a very capable and charismatic man. But he was completely broken by the death of his beloved, and drowned his sorrows until he became not even a shell of what he was before.
Jon Arryn as Hand was perfectly reasonable (he seems to have been the driving force behind the whole Rebellion, which indicates at least some level of competence, and as a Lord Paramount he certainly has the rank and popular respect, plus he was close to 3 other Lords Paramount).As Ned mentioned, Robert never knew the iron that is underneath Lyanna's beauty. Lyanna herself knew that Robert was a womaniser and concluded that marriage would not change that.
I would reckon that while Robert would not make a good king under the best circumstances, Lyanna's death made it even worse. Even if we just speak in game terms, look at his small council at the Crowned Stag bookmark. I don't know about you, but leaving Tywin entirely out and Jon Arryn as Hand are not the worst decisions he made in his reign. (The very fact that he made worse choices is appalling.)
I always assumed Littlefinger (who was a Jon Arryn appointment remember, originally recommended by his completely unbiased wife) was the main culprit behind the massive debts, if only because it seems effectively impossible for feasting and tourneys to actually cost that much. Well, him and the cost of the Rebellion itself (plus presumably left over debt from Aerys' reign; those pyromancy ingredients can't have been cheap).That Robert did, but he also undermined Jon's position by refusing to curb his spending. That single move brought so many troubles, I don't even know where to start the catalogue. But, here goes:
1) The Lannisters grew their power exponentially. With a lady of the house as Queen of the Iron Throne, it was already bad enough. Now, the Lannisters have the Crown by the balls due to the debts.
2) Littlefinger as Master of Coin. Oh boy...
3) The Iron Bank gets involved as well, which is never a good thing.

But yes, Robert was an excellent war leader but a mediocre king. I just don't see any realistic alternative (he was the only one with any legitimacy, which actually does matter in these cases; power resides where people believe it resides, but legitimacy is one of the things people believe in). Really, if Cersei had been less...Cersei, the Crown would have been in much better shape.
For that matter, if Lyanna hadn't died (and had actually been reasonably supportive of her husband Robert), Robert probably would have been a better king (both because the Lannisters would have been less powerful, and because she probably would have at least tried to curb some of Robert's self-destructive tendencies). That was probably the assumption the rebels were working under (remember that "Robert for king" was decided on not just before the Tower of Joy, but before the Sack). It's not clear exactly when Ned learned the full details of the Tower of Joy and Lyanna's situation, but it was probably during or shortly after the Sack, if only because I can't imagine him not having done something about it ahead of time otherwise. So as far as they were concerned, Lyanna was still alive and imprisoned by Rhaegar. By the time Ned gets to the Tower of Joy and everything that happened there, Robert was already king. Under the circumstances, Cersei is really the only feasible unmarried woman of age, and no one knows about her wackiness. Under the original scenario, Robert would have married Lyanna, who, while maybe not in love with him, would have at least put up with him and used her influence to keep him under control (she might not have been happy about that role, but when did medieval rulers, even Ned, care about what women thought?). It might very well have worked, as Lyanna doesn't strike me as the enabling type. Now, with hindsight that was a doomed plan, but at the time of the Battle of the Trident, it made perfect sense.
Instead, we got Cersei cuckolding, undermining and eventually murdering him, while Robert suffers serious mental problems (the fact that he keeps dreaming about killing Rhaegar every night is not a healthy sign), Ned isolating himself from the new regime (which is another place where Lyanna would probably have been useful, to promote closer contact and an earlier reconciliation), and Jon Arryn bringing in his wunderkid Littlefinger to help sort out the royal finances.
I think that Jamie did not know himself well on the genealogy and history, and thought like men who respects only strength and is not too honorable![]()
