The more of Tatum I see the tougher call I'm having. Right now I see four guys that are going to get significant time next year and a have an impact, and I have Ball at four for all the long discussed reasons (lack of athleticism, inability to be much more than a spot up shooter, etc.).
The more I see of Ball the more I put him in the "Could be a huge success if he lands in the right situation" class of draftee, whereas I think that Fultz, Jackson, & Tatum ultimately succeed no matter where they land. For example I think that Ball would be great on Philly, not so sure about LA or Phoenix, though.
I'm actually at the point where I think I prefer Boston drafting second. Fultz is a fantastic pick & roll player, but I think he may be more of a 1B type of player than pure alpha. I'm reaching the point where I might take Tatum over him.
Jackson may indeed be a shithead, which is a shame since he's sort of Kevin Garnett's Minime.
