With a Wall Street remake on the horizon, "Greed is good" is a fitting line for Chris Johnson. In the wake of a sensational second season in which he became the sixth NFL runner to eclipse the 2,000-yard plateau, the Tennessee Titans' Autobahn-fast halfback scoffs at the notion that he'll settle into the spoils of stardom and lose some of his drive. "I still have reasons to work hard," Johnson said last week. "Most people say, 'Are you hungry still?' I'm not hungry anymore ... I'm greedy. I graduated from hungry to greedy, and all I want is more."
