Yep. The Suns have done it with Chandler and Knight. Now the Lakers with Mozgov. If I am the league office, I do not like this. Teams should be trying to win games. It really messes up playoff seeding and playoff races when some teams are trying to win and some aren't. Your chances really depend upon your schedule toward the end of the year.
Not sure what to do about it, but tanking is not good for the league, especially when it is this blatant. I think that maybe limiting the number of top picks. Say no more than 1 number 1 pick every five years, and no top 3 picks two years in a row. At least perpetual tanking would be limited and there would be less teams doing it.
