If the 40 man balancing act isn't enough, Trov didn't even mention options, or how many times a player on the 40-man roster can be sent down to the minors during a single season.
Under the current rules (since the 2022 CBA), a player can be optioned to the minors no more than 5 times in one season. After that, if a team wants to send him down again, they have to designate him for assignment (DFA) — which means he’s exposed to waivers and can be claimed by another team.
And realize, SWR for example was send down, then returned. That two times.
He has 3 option left.
