Of course, this policy isn’t fool-proof. The 2004 Super Bowl is a prime example. Three players on the Carolina Panthers were found to have repeatedly filled prescriptions for steroids yet they never tested positive for steroid use. Supposedly, these prescriptions were for doses much higher than that generally used for testosterone replacement therapy.
So, even though the policies are there and are very strong, steroid use in the NFL is still present. When you have something that can give you such great physical benefits, it’s easy to see why the players are finding ways to use them. And, when some players use steroids they raise the competitive edge enough to possibly even convince those players who are on the line about steroid use to take the plunge and actually try it to save their careers and keep up in an ever increasingly competitive sports.
