Based on everything I've read about him, he's been on a meteoric trajectory since focusing solely on hoops after being a 2 sport (BB & FB) elite athlete. This type of recruit often turns out better than some who were ranked in the top 20 but seemed to hang around that initial ranking even though their game hasn't seemed to improve much.
Regardless of Colben's ranking, it's evident that the staff has zeroed in on him, seeing something special and great program fit. His shot and all around game continues to improve. And his rep as a call-upon lockdown defender has me sold on him.
