New ownership could do a lot of very beneficial things some of which are;
1 Stop micromanage the GM and stop allowing Bert Kolde/Vulcan to make decisions
2 Stop prioritize cash savings that provide zero roster talent (selling multiple draft picks, dumping players like Brogdon Hart Powell to cut luxury tax, dumping salary in another half dozen trades, not using the MLE or TPE)
3 Stop giving out horrible contracts to mediocre veterans that lead to problem #2
4 Pay luxury tax in a few seasons where its helps the team. It doesn't need to be Steve Balmer or 2000's Paul Allen SPAM spending, but just more than being one of the cheapest franchises in the league in recent years
5 Provide a tiny bit of a public appearance - Paul Allen did an annual training camp interview for the Blazers, other NBA ownership groups give communications to fans, the Blazers do and say nothing
6 Hire and empower a GM that has ONE long term strategic vision and works over multiple seasons to execute this. A selection should have started for this position the day Olshey was fired, instead the Blazers handed the keys to the cheapest interim GM available. Then when trading Dame the Blazers should have committed 100% to a long term rebuild - instead we acquired or held onto expensive veterans.
