It's not outside the realm of possibility that Kentucky has seven players drafted in June. Julius Randle, Willie Cauley-Stein, James Young, Aaron Harrison, Andrew Harrison, Dakari Johnson, Alex Poythress. All are likely to hear their name called if they declare. That's crazy. Having said that, it's likely that some of them elect to return to school (Johnson, the Harrisons and Poythress seem most likely to stay based on their likely draft position).
Bold prediction: of the group, I believe James Young will end up being the best pro.
