Sometimes younger brothers end up being the better athletes because they had to compete against their bigger/better brothers when they grow up. They are forced to elevate their game.
You will witness this next year when Jerami Grant arrives on campus. He's the best of a set of 3 brothers that have gone on to play high D1 basketball. The oldest brother who played at Clemson was definitely the worst of the 3. The middle brother, Jerian, is doing quite well at ND this year, though. Jerami will be better than both of them.
