"Except me," pointed out Severus. It wasn't that he didn't like Potions, Albus knew. He would have been delighted to teach only NEWT classes, but tended to describe his younger students as, quote, unconscionably stupid. He would much prefer, he insisted, teaching a class in which he did not need to try to instruct students in anything likely to cause large explosions until at least fifth year. But as much as Severus did not believe him, Albus still suspected that his potions master would be rather unhappy as a Defense professor. Too little of his favorite subject, and too many reminders of the war.
