Freshman Naz was on a good (though not great) team that pulled a #10 seed. He was behind quality guards/wings like Tyrus McGee, Will Clyburn, Chris Babb, and Korie Lucious.
Freshman Grill was on an awful team (especially after Haliburton went down, which is when Grill received the majority of his minutes) with two playable guards -- Tyrese plus Bolton. He couldn't manage to beat out Prentiss "Stepback" Nixon, Terrence "Bustorama" Lewis, and freshman Tre Jackson for minutes.
Freshman Eli is on a team projected as a #3 seed right now stuck being Kalscheur and Grill playing the best basketball of their lives and with the best SG play we've seen since Naz and Matt graduated plus Jaren Holmes, a grown man who looks like he should have finished college in approximately 2003.
Their minutes are inversely proportional to the quality of the teams. Put freshman Naz or freshman Grill on this roster, and I would imagine they'd barely see the court just as with Eli King right now.
