Here's a scouting report: http://nebraska.scout.com/3/CampCountdown.html
"Kool is simply a wonderful athlete, with a great upside and two years to develop into the position he’ll play in college. That’s up in the air as he’s got the versatility to play a variety of skill positions on the field. If he can gain a couple of inches and hit that coveted 6 foot mark or even more, that ups his stock dramatically. He’s already a solid athlete, but with so much time to develop, he could be another gem in the state of South Dakota."
