Jonny Be Good

If not for the strongest point guard crop since 2009, the story of the upcoming NBA draft would be the talented and versatile freshman forwards Josh Jackson, Jayson Tatum, Jonathan Isaac, and Miles Bridges. While Jackson (8.0 DMX), Tatum (7.7), and Bridges (7.0) have met or even exceeded lofty expectations, the real standout in my numbers has been Isaac (9.8), a wiry 6’10” combo forward with tantalizing two-way potential. After 27 NCAA games, Isaac grades out as the fourth best forward prospect since 2002, edging out Blake Griffin, Chris Bosh, and Ben Simmons. That begs the question, is Jonathan Isaac truly an elite prospect?

It is easy to see why the numbers adore Isaac. He is tall, young (19.7 years old on draft day), efficient, rebounds like a PF or C (11.2 REB/40), and has an elite combination of steals (1.8 Per 40) and blocks (2.3 Per 40). His only blemish statistically is a low assist rate, which is offset in the model by a relatively low turnover %. Moreover, he has done this in arguably the toughest conference in the NCAA and has helped the Seminoles to a #18 KenPom rating, up thirty spots from #48 last season.

Passing

Let’s go back to Isaac’s one conceivable red flag; his lack of assists. Between his statistical brilliance, age, tools, and team success, it seems pretty obvious that Jonathan Isaac is good. The question is whether or not Isaac is a prospect on the level of Bosh or Griffin as his projection suggests, and his passing may be a deal-breaker to that end.

In the NBA, passing the is skill that often differentiates the great from the good. This is pretty intuitive; players who are elite at creating for themselves and also for teammates are completely unstoppable. Since BPM is generally a good measurement of the value of NBA players, here is a list of the top 13 players by BPM along with their AST% this season:

PLAYER AST%
Russell Westbrook 56.5%
James Harden 50.7%
Chris Paul 49.7%
Giannis Antetokounmpo 26.5%
LeBron James 41.7%
Kevin Durant 22.6%
Nikola Jokic 27.3%
Draymond Green 28.3%
Kawhi Leonard 17.7%
DeMarcus Cousins 28.0%
Kyle Lowry 29.2%
Stephen Curry 28.8%
Jimmy Butler 23.3%
Jonathan Isaac 6.8%*

*NCAA

Only Kawhi Leonard, the league’s best perimeter defender and a ruthlessly efficient offensive player, has an AST% under 20%. Even if you expand the list to 50, the only non-center with an AST% lower than 10% is Otto Porter, who is leading the NBA in 3PT% and was an A:TO stud at Georgetown.

Historically great DMX projection aside, Isaac seems unlikely to achieve NBA superstardom barring a Durant-like leap as a passer (note: Isaac ain’t KD on offense). Markelle Fultz, a supremely talented offensive creator (Westbrook/Harden), and Lonzo Ball, an outlier passer and basketball genius (Paul/Curry), have far clearer, if still mathematically unlikely, paths to being top ten players. Even Josh Jackson (18.6 AST%) is still drawing live to be Jimmy Butler 2.0. Jonathan Isaac projects as a better version of Marvin Williams, a former #2 overall pick who has had a solid career as a stretch four and versatile rim-protector. I wouldn’t draft Isaac over Fultz, Ball, or Jackson, but he has played himself into my top five in a loaded class.
