The craziness of this pre-NBA Draft has been pretty incredible. In most drafts throughout history, there has been a frontrunner on who everyone thought would be selected first overall. After that, the rest of the draft was up for grabs but there was a general idea of who was going to be taken.
Take, for example, last season when Markelle Fultz was the undisputed first overall pick by the Celtics and then the 76ers. There was really no question that he was going to be picked first and that Lonzo Ball was going to be second. After that there was more variability, but those picks were not in question.
