Maybe I'm the outlier here, but I don't think there's a single player on the team whose game is so solid that they are locks for 30+ minutes. Jackson is a very good athlete and passer, but is loose with the ball and struggles to shoot. Richmond* hasn't shown at SU that he's a knockdown shooter, and Cole is short and shoots hot and cold. If they have obviously developed early on next year to the point that those are no longer problems, then sure, they get 30 minutes or more. And I hope that's the case. But you have to prove it.
*Assumes something that hasn't happened ... yet.
