They may be the two most devastating words in the sports universe: "torn ACL." Imagine that injury and its catastrophic implications on the knee. Imagine the rehab it takes to fully recover. Then imagine it happening again. On the same knee. At 15 years old. That's been the life of Detroit Country Day School's Chris Fowler. Fowler blew out his knee once at 10. Then again at 15. Two major reconstructive surgeries later, he's ready to star for the Detroit Country Day School basketball team.
