Steelers' safety Troy Polamalu is concerned with the recent influx of fines levied against his teammates and other defensive players across the NFL. "I think regarding the evolution of football, it's becoming more and more flag football, two-hand touch," Polamalu said. "We've really lost the essence of what real American football is about. I think it's probably all about money. They're not really concerned about safety. "When you see guys like Dick Butkus, the Ronnie Lotts, the Jack Tatums, these guys really went after people," Polamalu told reporters. "Now, they couldn't survive in this type of game. They wouldn't have enough money. They'd be paying fines all the time and they'd be suspended for a year after they do it two games in a row. It's kind of ridiculous."
