A complete rebuild would be an alternative. But it's a bit dangerous to start this season since the pick is only Top 6 protected. So the Raptors might tank for nothing, if they end up with the 7th-9th pick.

I personally think it's a waste to tear everything down. Yes, losing FVV was a big hit but there is still a decent core. Siakam and OG are still in their prime. There are still plenty of draft picks available after the Lillard trade to upgrade the team further without having to give up too much. And there is always the possibility of trading Lillard for picks if it doesn't work out after 2 seasons. I don't think Lillard will lose much trade value by then.
