“You see Kobe Bryant miss a jump shot, he’ll go back after the game and shoot it 100 times. That’s how Kasen is. When practice is over, if he didn’t run that right route, he wants to run that route right 25 times in a row before he goes into the locker room… I think that’s the mark of a great competitor in any sport.” --Former Washington HC Steve Sarkisian
