Using default choices for seasons setup.
Noticed that Motrezl who is a 3.5 star player sign with Detroit but was not mentioned in season preview as a key addition.
Checked across all teams and the Key Addition and Key Subtraction field is None for all teams.

Yep, seeing that too...wonder if maybe there isn't some key information available during season #1 to make those decisions that is available in future seasons....not sure.

Yes if there's not a prior season then I think it is going to generate these without the key additions and subtractions for the first season
