The Hawks were tanking from the start of the season. They did not land the best odds in the lottery, but at the third position in this draft the Hawks will be choosing between Marvin Bagley III and Luka Doncic.
Atlanta went with PF John Collins last year in the lottery so it would not make much sense to turn around and take Bagley this year, especially since neither are rim protectors. The Schroder experiment did not go as planned and could be traded this offseason, paving the way for Doncic to come in right away and be the primary ball handler/playmaker.
