It "could be a year" before WA reopens its Borders
"It will be months or even a year before Western Australia reopens its borders, the state's leader has said on the day it was originally slated to welcome interstate travellers once more."
And given the restrictions between Victoria and other states, and even between NSW and QLD, border restrictions shape as the biggest challenge to our next season.
As others have said, a "maxi" hub won't work for the NBL. Too expensive and not enough revenue. Temporarilly relocating the Melbourne clubs out of Melbourne and front-loading with away games, might work when its only two teams. But if border restrictions and the resulting quarantines are in place, then moving teams interstate in a timely fashion becomes almost impossible.
