The Draft Lottery has a witness from every team present. So if its getting fixed its with their knowledge.
But what are they “witnessing”? And why is the “convenient” team always the one that wins? Nicks get Ewing, Cavs get LeBron, Cavs get first pick again the year LeBron leaves, Hornets get Davis right after being sold by the league (and having a big trade blocked). Always the team the league would like to win the lottery does.
