The issue is the Dodgers can go on autopilot for 162 games, make sure their veteran starters are healthy, and steamroll through the playoffs - their farm system and IL roster are plenty deep to sleepwalk to 90+ wins.
I think the only way, absent the financial system actually getting fixed, to put the screws on their organization is for the rest of MLB to essentially boycott trading with the Dodgers, ultimately forcing then to have to flat out release or make available blocked prospects to the Rule 5 draft, and veterans coming off IL, getting nothing of value in return for them. That includes nobody selling them veteran reinforcements at the trade deadline, too. Force them to play with an aging roster or have to DFA valuable players.
