This is the NBA’s biggest problem going into this draft, IMO. Hornets I’m not sure deserve to be included in this group considering they just got some bad luck and I wouldn’t classify as tanking, but if the Magic, Rockets, Pistons and Thunder end up in the top 5 again (along with the Spurs) then there is going to be a clear issue with blatant tanking paying off.
There was a thread last year with some good ideas of how to discourage tanking… I like the idea of your natural odds being reduced based on the number of times you’ve recently had a top 4 pick. Say the top 6 end up Magic, Rockets, Pistons, Thunder, Hornets and Spurs (in any order) - then there is a clear cut case that only the Spurs and Hornets have not be serial tankers, and the Spurs clearly have the absolute best case for being given the highest preference.
Of course, there is a zero percent chance owners agree to make any substantive changes mid-season, but I can see some calls for serious lottery reform if one of these perma-tankers lands Wemby (or to a lesser extent, Scoot)
