Baseball

Whoever the buyer is they cannot "strip" the team down for parts and then walk away. MLB under Bud Selig attempted to do this in the early 2000s with the Twins and the Expos because MLB owned the Expos at that time.

The players association told MLB to go pound sand because they have a labor contract and they would sue and win. MLB backed down. Subsequently the Expos were allowed to move to DC and were sold to the Lerner Family.
Small market teams can succeed in baseball but they are unable to keep thier talent long term. A perfect example was the Royals run in 2014-2015. They won the series in 2015 but almost immediately started either trading or losing the talent to teams with bigger pockets. They have retooled and are currently battling the Yankees. The Twins won two world series on a combination of homegrown and free agent talent. They have some success in the 2000s as well.
