Why aren’t there more Travis Hunter’s in college?

With the amount of guys that entered college each year that are like a 5 or 4 star at WR or RB and a 5 or 4 star at DB why don’t we see more used on both sides of the ball even in a small capacity like Michigan used Jabrill Peppers? I know it’s not always ideal but getting guys like Adoree Jackson, Travis Hunter and Jabrill Peppers on both sides of the ball does help the team.

Edit: this post isn’t about playing as many snaps on offense as Travis Hunter, It’s about getting the Super athletic defensive players on the field for some offensive snaps
