So next year's roster:
Forwards: 3 on Scholarship Returning
Brock Jancek (WO)
Zach Kent
D.J. Burns
John Fulkerson
Guards: 4 on Scholarship Returning
Yves Pons
Lamonte Turner
Jacob Fleschman (WO)
Jalen Johnson
Jordan Bowden
Incoming: 5 Scholarships
Josiah-Jordan James (Guard)
Drew Pember (Forward)
Davonte Gaines (Forward)
Olivier Robinson-Nkamhoua (Forward)
Uros Plavsic (Center)
That's 12 on Scholarship next season the limit is 13. Bold = potentially gone by 2020 class based on graduation. Technically Jalen Johnson, John Fulkerson both could graduate after this season both will likely graduate as RS-Juniors and could leave or grad transfer.
So without knowing who from 2019 stays for 2020 and still having 1 spot, I don't see any reason not to snag another guy for this class. Even if he sits a year would be worth it, especially if a top 100 talent. You know 2020 you'll have at least 2 spots freeing up, could be more if James leaves for the draft or if anyone transfers out (Kent & Gaines would be my lead candidates to transfer after 2019 right now).
