I could be wrong, but technically we are still in the 2024-2025 season. It’s not even the actual offseason yet. So there are contract considerations until the Finals are over.
That's the gist of it. They can make deals sooner, as we saw Denver do a few years back, but typically they wait until draft night to start announcing deals. Until the draft though it's usually a waiting game. The league seems to prefer it that way as well so nothing detracts from the playoff coverage also.
