In racing, Nicky Hayden wins the all-heart category. You see him searching for that opening to gain a rhythm but crisp focus often eludes him. Even so, his approach has been good enough to win him a world championship and a spot in history. Dani Pedrosa is almost a pure rhythm (head) rider but only occasionally shows flashes of heart-driven brilliance. Lorenzo had a sweet balance of head and heart on 250s, and he has unquestionably reestablished that proportion in MotoGP. Stoner is the class leader in the head category of rider, he is all rhythm, as solid as they come. Outrageously solid, in fact. While he has perhaps relied too heavily on that strength in the past, with his departure from the sport imminent, we’ll never know where it might have gone.
