The #15 pick, Crabbe and Aminu for Porzingas? This relies very heavily on Orlando being incredibly stupid and irrational and I just don't think you can count on that anymore since they fired their GM.
I don't think very many people in the NBA would agree with you on that. Ball is a great play-maker, but his shot is considered suspect and his defense is currently terrible. He has a downside of a poor man's Rickey Rubio. I guess you could say he has an upside of Magic Johnson, but it's an incredible risk. Porzingas is still extremely young, has a great shot and has the potential to be one of the best rim-protectors and rebounders in the game. Prime Dirk Nowitzki on offense combined with prime Tyson Chandler on defense? I don't think any team would rather have Ball over Porzingas.
