NBL pushes back 20-21 season until after AFL and NRL finish.
The NBL will likely start towards the end of October now instead of the start of, buying the league another 3 weeks of time.
3 Weeks delay isn't long but I think it is a logical and reasonable start time based on the current trajectory we are heading in terms of Covid19 infections.
And also gives teams a bit more time to prepare given Free Agency was almost 2 months late.
