FILE - In this Jan. 2, 1984, file photo, Los Angeles Raiders Lyle Alzado gives a fist of victory after the Raiders beat the Pittsburgh Steelers in playoff fooball game in Los Angeles. With uneven testing for steroids and inconsistent punishment, college football players are packing on significant weight _ in some cases, 30 pounds or more in a single year _ without drawing much attention from their schools or the NCAA in a sport that earns tens of billions of dollars for teams Football's most infamous steroid user was Alzado, who became a star NFL defensive end in the 1970s and 80s before he admitted to juicing his entire career. He started in college, where the 190-pound freshman gained 40 pounds in one year. It was a 21 percent jump in body mass, a tremendous gain that far exceeded what researchers have seen in controlled, short-term studies of steroid use by athletes. Alzado died of brain cancer in 1992. (AP Photo, File)
