Mo Hurst is the premier 3tech inside penetrator in the draft it seems. I don't know if he would last until the second round if he gets cleared medically. Taven Bryan is the other high potential 3tech, he's mostly potential and athleticism though, would need to be coached up hard. His production was very much questionable in college, even though he did cause a lot of disruption and has obvious athletic talent. Rasheem Green is the third one I can think of.
