I have doubts Jaime could have killed Robert.
Robert was a beast in his prime. He was basically Mike Tyson, meaning he was just as strong as The Mountain and the Hound but, fast enough to keep up with anyone. Remember.....Jaime fought in no real wars until TWOTFK. He's called top 5 dead or alive without actually proving it in real battle. Robert was knee deep in wars by his 23rd birthday. If they're both wearing armor and mail, Jaime would have to be near-perfect and find the weak spot in Robert's armor. Meanwhile all Robert would need is one opening and his hammer would cave in Jaime's sternum, armor and all.
Jamie held his own against the Smiling Knight at 15 before Dayne killed him.
"At the age of fifteen, Jaime participated in the campaign against the Kingswood Brotherhood, during which he saved Lord Crakehall from Big Belly Ben and crossed swords with the psychotic Smiling Knight. He was knighted on the battlefield by SerArthur Dayne.[10]"


You gotta understand that Jamie is basically the Kobe of Westeros when it comes to the fight game.
Even Brienne gives him props but, says his legend was overstated. I'm just not buying he kills a Prime Robert, especially when one fights with a blunted weapon that's deadly against full plated armor and the other would just have a sword. I'm not buying it. Jaime was born in 266 AC. The Rebellion happened in 282-283 AC, which made him 16-17 years old. In other words, OLDER than Robb Stark was when he was out there winning battles, giving Tywin of all people that work. Robert and Ned were born in 262-263 AC. They're only 3-4 years older than Jaime. Which makes it sound even worse because y'all try to make it sound like Jaime's not in their era when he was. He had so much time to make a real name for himself and yet nothing.
This is about who the best fighters are. The hell are you talking about Robb and Tywin military strategies for
You started off using the Ned/Jamie fight from the show that never happened to prove that Jamie was overrated. And the only noteworthy dude he went dolo with is Rhaegar, who again was pretty good, and injured Robert, but Robert got the W. Most that's said about Robert is again, he was a fearsome dude and strong as shyt, and pretty good in the melee (no mention of him winning one). 
word on the streets is Herrera giving out that work
He charged a whole army by himself, got yoked up, thrown in a cell, starved for a year and lost his swordhand. I'll put that in plain english. He's dumb. For a "skilled" fighter, he's dumb. IF JAIME DID THAT DURING THE REBELLION, HE WOULD HAVE GOTTEN KILLED
And that would be the end of his story
