It seems to me they took the best player available in Noel last year and the BPsA in Saric and Embiid this year, so what does it matter that they can't/couldn't play their first year? Teams that are good draft and stash Euros all the time, nobody said a team in the lottery wasn't allowed to do that. People want the Sixers to be ashamed of their record and make desperation, short-term moves but they refuse to make that mistake.
Besides, even if Noel or Embiid played their first year the team still would have been horrible, I mean these kids are 19 years old. It wouldn't have had a huge impact on their tanking ability.
People should be upset at the system, not the Sixers for exploiting it. In other words, don't hate the player, hate the game.
