Status of the roster for fall 2019:
Seniors (1): Isaiah Roby
Juniors (4): Dachon Burke, Thorir Thorbjarnarson, Nana Akenten, Jervay Green*
Sophomores (2): Amir Harris, Brady Heiman, Justin Costello (WO)
Freshmen (3): Karrington Davis, Mika Adams-Woods*, Akol Arop*
* Not on campus yet
Leaving team: Glynn Watson, Isaac Copeland, James Palmer Jr., Tanner Borchardt, Thomas Allen
That leaves at least 3 scholarships open. I think Roby will return. I don't know if Nana Akenten will return (suspect not). Johnny Trueblood is considering returning in some capacity, but I would be surprised if he ends up on scholarship. I have no idea what Karrington Davis could contribute or if his injuries will let him - he was another Kenya Hunter recruit. There has been a rumor that Thor would go play professionally in Iceland.
There are a few guys that the previous staff offered that might fit in - 2019 HS SR PF/C David Skogman looks like he has potential to be a center in the big ten. C Emmanuel Ugboh from IWCC is another that already has an offer that looks like he has the body to be a Big Ten center.
I have no idea who the assistants already have a relationship with, I suspect that they have better options than the two I mentioned above. Getting 4 players at the last moment really sounds risky. A grad transfer or two would be ideal to balance the senior class a little.
There are a couple of players that could use a redshirt year (Brady Heiman, Akol Arop). There are football players who could help out, but I doubt that would happen. Would be fun if Austin Allen and Noah Vedral found their way over to Hendrcks.
So many questions on the roster, and you have to hope that Hoiberg can balance the desire to build a team around Roby and the need to build a foundation.
