You should be able to gauge if one or both the scoring categories is a “massive” growth opportunity by the middle of the year or so, based on how they develop at 5-6 for a dozen+ games. If one of them is growing faster, that’s the one I would kick up to 20 first, possibly before the end of the freshman year. I would plan on him not accepting a sophomore redshirt, though you could get lucky. This way, he starts the sophomore season, when you don’t yet need him to score, as a 75/50+/75 Ath/Spd/Def guy, who is perfectly capable of starting for you. I would scale back the defense minutes, along with ball handling (I’d keep more minutes on passing, personally, until he crosses 30 or so, which could take a couple seasons starting that low), and start the sophomore season with one of the scoring categories at 20.
He’ll be a beast by the start of his 3rd year, and then you can start developing the other scoring option. May not completely max (although I wouldn’t rule it out with that work ethic, especially if you can start him 3 seasons), but he’ll be POY caliber anyway, if one or both of those scoring options is super high.
