I was in a bit of a rush, so apologies for the vagueness.
Samba Kane is a 7-foot freshman who was expected to be a starter for Illinois this year (largely because every other post player they had has left).
This now leaves them with just Giorgi Bezhanishvili, who looks like a cross between Nikko and Jontay. Actually probably fits Underwood's style better than any other big they've had, but he's not exactly the most fleet of foot. He'll probably average 3 points per game but score 15 vs. us.
