Saying that a GM should always have a suitable replacement for a star level player might be a stretch.Especially considering the disparity of payrolls around the league.Tampa Bay can't reasonably have an answer to losing a star player in August.Doesn't seem like you have an answer for who benefits from ditching the August waiver deadline.
I think small-market teams specifically benefit from the ditching of the August waiver deadline. Good teams, who have a real need for a specific player, can easily get blocked by their opponents (with worse records or in the other league) making waiver claims on that specific player. But there is an asymmetry there, as small-market teams are probably more reluctant to make a defensive claim on an expensive player that would help their opponents because they can ill-afford to be saddled with the salary.
Personally, I wish they would have just moved the regular trade deadline to August 31.
