Most positions don't come open until early April and May. That's when contracts are done.

Only job I've heard about is the one here in Lubbock. It's Lubbock All Saints Episcopal School (JH FB/Golf).
Rumor is they're adding a FULL high school within the next 2 years and they will start playing TAPPS sports....
