So far Dilly's season is the real deal. I'm a huge Topic fan but my biggest hangup about Topic is I'm still not sure of the strength of the Adriatic league. Luka dominated in ACB and Sengun dominated in Turkish BSL, both of which are really good European leagues. If Adriatic league is not nearly on par with those two leagues, then a lot of Topic's numbers and projections fall apart. That's not to say he'll be a bad player, there's just a lot more uncertainty with him than with the other prior teenage wunderkinds.
Regarding Dilly, the link above shows Kentucky guards in the last 10 years with AST% > 10, BPM > 4, and USG >10. I really wanted to compared college numbers for Dilly and Sheppard with similar sized guys like Maxey, Monk, Fox, TyTy, and Cason Wallace. All the other guys on the list are much bigger and don't apply. What I see is that Dilly is able to create more efficient offense with a higher AST% and lower TO% than Fox. Sheppard has even more absurd numbers but you can tell by his AST% that he isn't quite the driver of offense compared to Dilly. He also has one of the highest eFG% of any of the guards, mostly driven by his excellent 3 point rate and 3 point percentages.
Regarding his defense, he is about the same size with similar wingspan (around 6'3" in shoes, + wingspan) as guys like Fox, Monk, Trae Young, Maxey, etc. All those guys are currently sitting between -1 and 0 defensive EPM which, while not terrific, is certainly acceptable for a point guard. He also has a higher ST% and TRB% than pretty much everyone else on this list, suggesting that he may not be a complete defensive liability moving forward in spite of his frame. (You can also see just how formidable a defensive backcourt of SGA and Cason Wallace is by these numbers). I read somewhere that the guy is half Samoan and should expected to put on even more weight moving forward, which would help him hold up on the defensive end.
Essentially, halfway through the season Dilly compares favorably to his prior Kentucky guard predecessors. His ceiling is something like a slightly worse version of De'aaron fox if only because fox has speed that Dilly does not and managed to develop his 3 point shooting to an elite level. He compares pretty favorably to Maxey in every way statistically but Maxey has also developed way better than how he was projected. Regarding where he should go, fox went 5th in what was considered a relatively strong draft in 2017 with more warts in his profile (namely his shooting). If Dilly continues to show out, there's no reason he shouldn't be a top 5 pick in this weaker draft.
