Saffie is not unique among the trainers.
Their overages mostly fall between pushing the envelope, being a little disorganized, etc..
the overages are not the medications that moving horses up 10 points and causing their stamina to increase. Those medications are 'ahead of the testers', or in other words virtually undetectable.
an average fan or player's perception, and the media's limited understanding along with the industries limited options of action as well as having to act in their best interests, it's just the tip of the iceberg, and they don't even accurately see the iceberg, they see a small island/islet? or whatever the hell an iceberg could be mistaken for.
in the nfl
fans believe that the NFL tests for steroids and growth hormones etc...
the NFL owners (the ones that care or look) and the guys the owners pay to help think, and the team employees etc. etc.. know full well what the deal is. It would be super expensive and a pain in the neck to try to stay ahead of the users. It would also make many of the players less super-human in looks and performance. They'd have a tougher time recovering from contact and injuries and returning from big injuries and surgeries, and playing extra years on their contract.
All of this would also negatively affect the advertising contracts.
long story short, the NFL unspoken allows the steroids and growth hormones etc... they make an example of a few players each year to show that they 'enforce' the no steroids/growth hormones/etc.. rule.
The majority of fans believe that the NFL is clean and if they can see/believe that a villain player or a few players with freakish physiques are using gear, then most fans take that as a rarity in a mostly clean and enforced sport.
in pro wrestling or pro bodybuilding
i think almost everyone understands that these guys are using a ton of gear.
there's surely a few out there who think it's clean or that cheating is rare, and there's probably a pro Wrestling segment that simply doesn't think much about things, but generally everyone knows, no one cares. The sports deny it and do some light propaganda, but you have to be the biggest freier, the most naive person to be an adult and spend more than 5 minutes watching the sport and not know. It's just part of the sport and entertainment.
Unfortunately our game is now in 'NFL' territory.
