Sports: A confession, and a puzzlement. Lance Armstrong has confessed. The seven-time winner of cycling’s Tour de France — titles which have been stripped by regulatory agencies — admitted to Oprah Winfrey in an interview broadcast Thursday that he had taken various performance-enhancing drugs and done blood doping during all of those races. The confessions ended years of strenuous denials that he had never used any such substances during his career. “There will be people who hear this and never forgive me,” Armstrong said. “I understand that.” The second part of the interview airs tonight on Winfrey’s OWN cable channel, which is not carried on most local cable systems… Meanwhile, the strange saga of Notre Dame All-American linebacker Manti T’eo and the supposed hoax involving a girlfriend who supposedly died last fall gets stranger. The scheme, at least at this point, appears to involve some form of “catfishing” — a term taken from a cable-TV show three years ago that documented how some people create fake online profiles in order to find romance. The website Deadspin, which broke the T’eo story, blames the hoax on a 22-year-old from California. Notre Dame is standing behind T’eo, saying he was duped… Prep sports: There was none last night, thanks to the snow which caused school systems to cancel Thursday’s schedule. Assuming roads clear, a slate of basketball games is on tap for Friday night, including Oak Grove at Fultondale, Gardendale at Hewitt-Trussville and Carbon Hill at Corner.
