Now, this really makes no sense. They demoted him to the PS. only to elevate him immediately, with no roster transactions in between. And his contract is all base salary, so there are no extra bonuses tied to being on the roster at a certain date.

Maybe they thought they were going to do something, and then decided not to (such as poach another player from another team's PS - maybe that player was taken by another team)? Is there some weird rule that says you can't make a claim on another team's PS player unless you already have an open spot on your 53 (vs. making the claim, having it completed, and THEN making the move to clear a space)?

Otherwise, what purpose could this possibly have served other than to frustrate/confuse Melton?
