If the season is cancelled, the Basketball Related Income for this season will take a massive hit. Depending on how everything is handled(meaning no smoothing of cap numbers) the salary cap could not just be lower than projections, but lower than in 2019-20.
That means for free agents, or players with opt outs that can become free agents, their new max salaries and contracts in general could be much lower in 2020-21 as compared to 2021-22. So for these players with opt out clauses, maybe it makes more sense to take the payday next year and opt out in 2021 where more teams will have money and the salaries will be much higher after a full 2020-21 season.
So given all this, does it make it a no brainer for Hayward to not opt out, play next year in Boston and become a free agent in 2021? I think it does. I think it just about guarantees Hayward is back next year, which I think is a good thing.
