Just want everyone to remember something. Last year the consensus was Simmons #1, Ingram #2, then anyone of 5 players being in the mix for the third spot due to how close those players were. Most draft sites had Jaylen Brown down near 8th. Only a couple had Jaylen going third.
Why should we remember this? Because I really believe that the talent, 1 through 7 is so close that all it could take is one or two GMs falling in love with a player for a consensus to be thrown all to hell.
So I wouldn't etch in stone that the top 4 are Fultz, Ball, Jackson, Tatum. I especially can see Jackson tumbling down the draft if teams start interviewing coaches, trainers, and others and find out he has massive maturity and good decision making problems.
