There's a conversation to be had about who will eventually be the best player in this draft. But as to who's the best player right now, it's Davion Mitchell and it's not close. NBA teams get trapped by consensus and stagnant thinking way too often so a consensus develops and people just run with it. Mitchell is so dominant in that tape, it's just absurd. His ability to shoot makes it easier for him to drive and his driving ability makes it easier for him to shoot. The closest comparisons I have are Baron Davis and Steve Francis. Maybe not as explosive at finishing around the rim, but in terms of getting to the rim, he's right there next to them. He will be able to get the rim at will in the NBA. He's too fast and his ball-handling is too tight.
The only question is his shooting. 44.7% from the 3-point line on 4.7 3's a game but only 64.1% from the ft line. I don't know what happened at the free-throw line, but I'm going to take his 3-point percentage as being indicative of how he'll shoot in the NBA. Attacking the hoop Mitchell just toys with defenders. His offensive skill level is already so high. Two dribble pull-ups, one dribble pull-ups with ease and perfect rhythm. NBA athletes are good, but they are not going to be able to stop him. Offensively, teams will either have to put their best defenders on him (and even then it's going to be tough) or they will have to help. His passing/playmaking shows a level of dynamism (i.e. he is able to read/analyze/react seamlessly).
I think there's a case to be made that Mitchell should go #1. Because of his height you can drop him down, but Mitchell will be a bonafide star. Not to mention he has all-NBA defense potential. More than any of that, though, Mitchell has it. There's an old joke that the only person that could slow down Michael Jordan was Dean Smith. When Mitchell is unleashed on the NBA, people will see just how much the structure at Baylor slowed him. In the pace and space game of the NBA Mitchell will be unstoppable. As his offensive game gets more multi-faceted - i.e. he adds in floaters and more creative finishes around the hoop (I would love if he watched some Tony Parker) - he's going to become even more dominant.
The argument against Mitchell is that his shooting is a fluke and his lack of size will lead to him being exploited on the defensive end. These are fair criticisms, but for me there's simply too much good tape of him knocking down shots. And you can see that he shoots with no hesitation. As far as the size goes, it's true teams will be able to exploit the lack of size, but they will also have to stop him. Mitchell will be a player that opposing teams will have to provide help to stop. In a league that loves to switch, even the most athletic big men will struggle to guard him much less average big men.
Needless to say but the Wizards should really try to trade up for him. I know I said the same thing about Kispert, but Kispert at his best is a player that needs to play off of another star. Mitchell has the ability to be that star. I'd take him over Kuminga and he should be in the conversation for the #1 pick.
