Mcclain revealed at his pro day that he has Crohns disease dont know what this means for his draft stock but it defineytly is something that might be put in consideration. David Garrad also has the disease so im guessing it doesnt affect you on the field that much. maybe this would probably drop him out of the top ten who knows theres so many factors pre draft that occur unexpectedly and in some ways could end up benifiting a team
