If they do re-set in 2020 and go over in 2021 and 2022, presumably they'd be right back in the same position of wanting to re-set in 2023. Which means they would have to be very careful about the long-term commitments in 2021 and 2022. Sort of a Catch-22, isn't it?
Also, the current CBA expires at the end of 2021, and everything after that is kind of up in the air.
Just pointing out that there's nothing simple about any of it...
