which player leads the league in per requiring at least 15 games played and playing less than 20 minutes a game this season under the age of 24

I couldn't find anything for this season, but Day'Ron Sharpe had the best PER by a player younger than 24 with 15+ games played and fewer than 20.0 minutes per game in 2024-25, with a 19.8 rating.
