Kevin Young started his career as an assistant and then an associate head coach with the Phoenix Suns before BYU signed him last spring. Prior to making the switch to college, he'd been widely viewed as a future NBA head coach. It's easy to see why. During Young's time with the Suns, they finished top 10 in the league in offensive efficiency three times. And when he was hired by the Cougars, he brought an NBA approach with him, including hiring multiple analytics experts to help the team reach its peak. It took some time, but BYU has owned the nation's top offense — yes, over Florida, Duke and everybody else you can think of — since Feb. 11. Richie Saunders is the leader of that offense, scoring 25 points against Wisconsin on Saturday. And now, the Cougars will make their first trip to the Sweet 16 since Jimmer Fredette led them there in 2011.
