I feel like Jaime's a combination of the last two posts. In the books he was an amazing swordsman, I don't think it was too exaggerated. He had competition but he was up there for best fighter in Westeros. That's all he was though, a great swordsman. In a fight he might be able to kill a couple men, but that's not going to turn the tide of the war and he's not going to single handedly (
) win a battle. When it came to commanding he was too rash and uncalculating. Whether it was pushing Bran off the tower or hunting down Eddard, the Lord of Winterfell and Hand of the King, he seemed to be impulsive. And both of those instances failed miserable, Bran survived and Ned was injured stopping Tywin's plan of luring Ned and kidnapping him.
