It’s not completely clear to me why a long snapper specialist would need to use steroids to improve his play.
I’d think the hyped-up reaction that often accompanies steroid use would result in 60 yard snaps over the punters head.
Remember what they tested positive for was a diuretic which is considered a masking agent, both of steroids and other banned substances including of the recreational variety. Technically speaking they’re only getting busted for hiding evidence, not for steroids or any other specific usage violation.
