FILE - This July 30, 2011, file photo, shows Ben Lamaak of the Oakland Raiders NFL football team. 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. Lamaak, who arrived at Iowa State in 2006, said he weighed 225 pounds in high school and 262 pounds in the summer of his freshman year on the Cyclones football team. A year later, official rosters showed the former basketball player from Cedar Rapids weighed 306, a gain of 81 pounds since high school. He graduated as a 320-pound offensive lineman and said he did it all naturally. "I was just a young kid at that time, and I was still growing into my body,” he said. “It really wasn't that hard for me to gain the weight. I had fun doing it. I love to eat. It wasn't a problem."
