You said we’ll be a lottery team for the next 5 years meaning non playoff team not contender.
We have Schröder, Prince and Collins to build with. If we draft a Marvin over a Paul or a Sheldon Williams then you’re right on the timeline but it’s impossible to predict.
If we do hit on the next two drafts and Collins/Prince keep progressing than I think we can be a playoff team in 2-3 years. Yes I know easier said than done.
