The manual (i dont have a pic, im on mobile) says teams are not allowed to choose their stations for playoffs. This should mean the alliance captain will have the left station and the 2nd pick in the right (viewing from outside/behind the arena). At a regional in 2019, I was on the left as a 1st pick, our captains were center and 2nd pick on the right.
Championship Hopper: 254, 148, 2976 were in the right, center, and left respectively.
Was this simply a rule that was not updated?
