Probably because of this:
I’ve always thought the dumbest part of this PR dance is that the star player must be solemnly cut from his original team, but because we love redemption he can eventually come back to play – but not for the original team! They’ve moved on!
As a fan it must seem silly that all the facts are still the same and now some other team gets that player’s output.
With that said, we may be in a new era where video evidence is enough to keep these guys out permanently.
