Battle tactics.He was a great military leader.With the sword he's nowhere near the big dogs.Hes not lefty Lannister status but he's just average.
What's done is done. Respect the king in the north. It's not like he got out maneuvered or outworked, he got betrayed...
That being said, I wonder where he ranks on a swordsman power ranking. He's described as a beast in battle. I wonder if that comes from skills, or battle tactics.
