One issue we?ve had in this league in the past is workload for commishes and others processing transactions so might be best during a more quiet period.
I think it should definitely be after whenever MLB does it but doesn?t have to be immediate. Maybe like around spring training or start of season once most all the FA transactions are processed.
Regardless, I think it should mostly be up to the league executives handling the transactions. Whatever works best for them in regards to the management. This league takes a lot of admin work so whatever helps reduce that, as long as it?s after MLBs date is fine by me
