I don't really have many (if any) hopes for Rhyan at this point but I do feel it bears mentioning that "PEDs" can cover a wide variety of substances taken for a variety of reasons and as far as I know it was never disclosed what Rhyan was found to be taking and/or for what purpose.
Obviously "Performance-enhancing drugs" implies something that enhances performance (duh), but I think the easy assumption is to take that to mean he was on something that would give him an edge on the field - stronger, faster, more endurance, etc - and that even with this unnatural edge he wasn't able to beat out his competition to get on the field.
And let me be clear that this may have well been the case. But it might not have been, either. People take steroids/PEDs for a variety of reasons. Some of those are certainly to add strength, get stronger and faster, and so on. But other times it's to recover quicker from an injury. It's to help decrease recovery time between workouts. And so on. So I don't really have any idea what exactly he was doing and for what reason, but all that to say that I don't entirely agree with the notion that he wasn't able to get on the field with the aid of PEDs so therefore he definitely won't be able to without them.
