Its getting more press because the other leagues are suppressing it. It is not hard too believe that there is an immense amount of PED use in NFL (way too much money on the line) and probably the NBA and Soccer.
The NFL really should have some kind of amnesty about past PED use so that sports doctors can share what they've learned with the broader medical community. It's actually incredible how NFL players can bounce back from serious injuries. Sharing those secrets could really help a lot of people.
