If he can improve his footwork, the Huskers might play "big" more often with Roby at the 3 with Copeland & Tshimanga both on the court, but that might cause rotation issues if Heiman isn't ready to play immediately because Borchardt plays hard, but won't get much PT in conference play because he's not quick enough. Tshimanga only played 13 minutes a game last year & I think he would probably get 20-22 in the 18/19 season.
I'd like to see Jordy get more time because I've seen flashes of talent, but the consistency of his footwork will have to take a huge jump to get starter type minutes (25-30). He's only been playing organized basketball for 5-6 years so a big jump is possible.
