Young is more than a shooter, he's a great playmaker. He had 11 double doubles this year with assists out of the 32 games he played. He ranked 46th all time in the total number of assists he had this year.
Looking at that list there are some players who were busts, like Kendall Marshall is 3rd for most assists in a NCAA season, but he couldn't shoot. Steph Curry and Nash are the players he's compared to the most and he's been sort of a mix of the two, with Nash's playmaking and Curry's shooting touch and range. He won't be an MVP in the pros, that's expecting too much, but he should easily be a top 10 PG within his 2nd or 3rd year and help make his teammates better right away.
His best game was against NorthWestern when he scored 26 and had 22 assists. That's impressive on it's own but in the 29 minutes he was on the floor he was responsible for all of the Sooners points. He had a 100% assist percentage, which you don't see often at any level. Here is the
boxscore for the Oklahoma vs NorthWestern game. I know NW isn't a good college program but Oklahoma aren't very good either. Without Young they wouldn't have made the NCAA Tournament and they'll probably be pretty bad next year. You can knock him for going to a school like that but his shooting talent and passing ability should translate to the next level.
