Okay, the 'official' response I received to this inquiry was "Stars are relative to the league strength, and before the draft it's just an estimate, since teams have no players yet. Hence things may change after the draft."
Now I
get that, but would and will argue that there needs to be 1) a bit more of a consistency in the range of changes and 2) the front end system may well be improved if the pool itself were tightened up in terms of evaluating top tier candidates. That way the higher rated would probably remain the higher rated after the teams distribute. It's a bit unfair to assess a player as 1/5 star in a pool that may contain 200 1/1 star players that will end up in the undrafted FA pool once a league completes the inaugural.
ANYway, there's where it stands. On the one hand, small 'tatoes, it's a one-time thing; on the other, it's the very basis of a league's origin and its consequences will carry on for at least the first few years of your team.
