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)
