Cycling analyst John Eustice: Armstrong cortisone claim 'big'

In the first installment of his interview with Oprah Winfrey that aired Thursday night, now-disgraced cyclist Lance Armstrong described himself as "deeply flawed," and "a bully.” Armstrong who was recently asked to return his bronze medal from the Olympics was also stripped of his seven Tour de France titles after the U.S. Anti-Doping Agency accused Armstrong last October of being involved in a sophisticated doping program.

During the interview, Armstrong discussed using an array of substances like testosterone and human growth hormone, as well as EPO - a hormone naturally produced by human kidneys to stimulate red blood cell production in addition to blood transfusions. This morning two-time U.S. professional cycling champion and cycling Coach John Eustice weighs in on the first 90-minute interview and possibilities from the second installment set to be broadcast Friday night.
