It’s great experience and exposure for him. The only thing I worry about is every year 60+ are told they have a first round grade, and obviously only 30 are taken in the first.
Add to that that being a late first round pick doesn't really guarantee a player all that much beyond the first contract. Guys who get picked outside the lottery can struggle to even break a rotation their first year or two and in some cases even end up splitting time between the big club and the G League. Take a look at picks 17-30 from lat year. A handful of those guys are playing and thriving, but a lot of them are nailed to the bench or plying their trade with the G League affiliate.
