Let's just breakdown the contracts over the upcoming seasons.
This season - it's not a big deal. We can trade Favors along with one of Thabo, Udoh, Neto/Bradley, Neto/Niang, Bradley/Niang.
Next season, I also don't think it's that big of a deal. Gobert, Mitchell, Korver, Crowder, O'Neale, Grayson, Exum, Ingles, Bradley, Niang are all under contract for next year. If we wanted to keep Rubio, Thabo or Udoh, we could since we have their rights.
2020-21 is when it gets interesting. We would need to re-sign Crowder, Korver and O'Neale (restricted free agent) while also having options for Grayson, Bradley, Niang. We could sign Mitchell to an extension, but I'm pretty sure he would be in his last cheap year.
2021-22 we are needing to re-sign Gobert, Exum and Ingles while Mitchell's first big contract hits the books. This is the first year the contract could really get in the way of keeping everything together.
2022-23 the contract is expiring at this point which maybe means it could be waived and stretched if we desperately had to. Or we can try to trade his large expiring.
