Conner Kraft is the interesting one left in North Dakota. Have seen some say he's the best player in the class for North Dakota (in a class with 3 other guys committed to d1 schools). He played AAU for Howard Pulley. I believe when coaches could start talking to players in this class he had heard from some high mid major and even a couple of p5 programs. I would think he would be a d1 level player based on that but haven't seen him report any offers.
I think Zach Kraft is probably skilled enough to play d1 basketball but size and frame will always be a limiting factor for him
