Their all skilled at teaching and their pretty smart so isnt that good for a teacher a hhad full of them are aurors.
The position is cursed so…
Because they all already had their jobs and Dumbledòre probably knew the position was cursed
I this because the order was busy trying to really people to their cause
Which order member exactly @Thejigglenut ?
Well, Lupin was a DADA teacher, he was in the Order. Same with Moody, even though technically it wasn't really Moody. And also Snape. So he did have Order members teach DADA, just not every year.
They all had stuff to do. They were trying to stop Voldemort from gaining power.
What do you think?
