NO END INSIGHT: Jimmie Johnson and Chad Knaus claim Cup No. 6 - and have plenty left in the tank

摘要

ELITE COMPETITORS, LIKE newly minted six-time NASCAR Sprint Cup Series champion Jimmie Johnson, have it. They always have, and they always will. No worthy champion achieves anything without it. Michael Jordan had it during those magical years with the Chicago Bulls. Tiger Woods had it before foolishly throwing it away. The Boston Celtics and Arnold Palmer and "Mr. October" Reggie Jackson had it. "I am the greatest" Muhammad Ali had it. So did Wayne "The Great One" Gretzky. And, don't laugh, but Terry Bradshaw had it, too.
