Martinez and Toffoli both warrant a 2nd and a prospect by themselves, as well as the condition on Toffoli.
In that case, Martinez would return a 2020 2nd and Kylington, Toffoli would return a 2021 2nd (which upgrades to a 2021 1st if he re-signs) and another B/B+ prospect. As OldNYIfan said, we're good on goaltenders, so Ruzicka would probably have to do. You can have salary retention on one, but not both, as the Kings would then be maxed out at retention contracts until July 1, and they might want to make additional moves at the draft.
