Technical chops are important indeed, I'd say in a 40-60 proportion with attitude, respectively.
From my previous work (when I was a Manager), I know a 98% attitude dude who is deep roots into the post and cannot be fired. No one wants to fire him, he's too loyal to the company; but he's also very hard to work with technically-wise. He just doesn't have it, he sometimes screws up a simple upload CSV file procedure, and his mistakes have costed several thousand dollars over many months to the company he works for.
The political cost of firing someone like him is just too high for any Senior Manager there. He is regarded as a force-to-be-reckoned-with in terms of cultural fit, but on the financial sheets, he's just deep into the hole.
You can always skill up some technical knowledge you might have, but attitude is hard to build. However, no extreme is good, as you put it by being over-educated.
