However, this competitive advantage that favors players who are willing to subject their bodies to opiates - far more harmful than HGH - or even avoiding the concussion protocol already exists.

Modern medicine says that professional football is a deadly and debilitating occupation. It bans harmless recreational drugs while it's labor force medicates with alcohol and pain killers. This absurdly hypocritical drug policy helps the league maintain a facade of supporting players' wellbeing. Meanwhile, the money machine that is the NFL has no problem filling it's broadcast booths with retired players to promote its image. HGH is an evidence based treatment, same as Percocet, but the league has too much to lose to change anything.
