I use to keep nbadrafttiers.com up. Had a lot of followers, but couldn't figure out a way to monetize to make it worth the amount of time I was taking from my family.
I'm not an expert though.
I'm really unimpressed with anyone past the top 5 this year. Honestly, Grayson Allen is the 6th best player in this draft.
Michael Porter has some legit questions about his game. From what I've heard he may be unlikely to go into the draft this year anyway.
For me, it goes 1) Doncic 2) Bagley 3) Ayton 4) Bamba 5) Porter.
I really like a kid from UCLA named Kris Wilkes. I also think the wing from Kentucky is a good prospect - Kevin Knox. I know Allen is a head case, but he has the ability to be a better Evan Fournier. Miles Bridges, Robert Williams, Trae Young, and Isaac Bonga (Germany) round out the top 12 to me.
High end comparisons might help you see how I gauge them so far.
Doncic - Better Gordan Hayward (plays with great pace and body control, but has better court vision)
Bagley - Chris Bosh (lean crafty scorer from the inside and outside)
Ayton - Jermaine O'neil (a bit rigid, but great body with a pretty good feel)
Bamba - Gobert/Steven Adams (defensive centrifuge with limited offensive feel)
Porter - Rashard Lewis/Kris Middleton (great scoring instincts)
Allen - Oladipo/Fournier (great shot creator whose game should be even better with an open court in the pros)
Wilkes - Trevor Arize-heavy (really good athlete with great defensive instincts and raw driving power)
Knox - Rudy Gay (scorer)
Bridges - Julius Randle (crafty left hander with passing and defensive potential)
Williams - Cody Zeller with shot blocking (developing feel for helping the offense keep moving and a good defensive instincts although lazy)
Trae Young - Jrue Holliday (crafty high volume scorer with pretty good court vision)
Isaac Bonga - Nic Batum (great physique and court vision)
I like some of your comparisons. But I really do at the same time, dislike how we try to fit player's mold into cookie-cutting. Doncic doesn't seem like any player I've seen play from Euro, his skillset offensively is just light years ahead of his college peers in the NCAA, and definitely above most professional European players. That being said, while his skill and his vision is extremely high, and he's very young, I definitely have question marks about what his best position would be, and his defense.
And why do you have Grayson Allen as the 6th best player over Trae Young, who's having a stellar season? Just curious, I'm very high on Bagley, who I think will eventually get the KAT treatment.
I agree about player comparisons. They fall woefully short in actually scouting a player. That said, as a short summary of the players in a draft class, it can be helpful. Again, you can't reduce a player, because each player has an irreducable complexity ...
For that reason, when I do comparisons, I try to find a player's defining characteristics (normally just 1-2) and find a current successful NBA player with those same characteristics.
I agree with you on Doncic. He's one of the toughest comparisons. I went with Hayward because of the way that both players play at their own steady pace, but both are crafty, deceptively athletic, and able to get to where they want on the court. The think is that Doncic looks like he has much higher upside as a passer.
As far as Allen goes, I'm a sucker for lateral explosiveness (changing direction, jumping off one foot, eurosteps, etc.). Its one of the underrated athletic abilities in the NBA. Grayson Allen is a pretty good athlete, but his lateral explosiveness is elite. Combine that with his shooting and scoring knack and his NBA size for NBA two-guard, and I think he is a really underrated prospect. There are definitely other concerns with him, but his basketball abilities are special, and there is something to be said about playing and starring for Coach K.
I haven't seen enough of Young, but I do like him. I don't see the same kind of athleticism with Young, and so far, he hasn't been a great shooter. I will be really interested to see him in Big 12 play against Kansas, Texas, etc. If he has big games against NBA level athletes, then he might continue to rise on my list.
