I think we have to remember the tremendous pressure that most fighters are operating under. Aside from the factors of putting food on the table and a short career span, the gap between the true genetic freaks the run of the mill joe is vast.
I've rolled with guys that I know for a fact never took a thing in their lives and they were still so ridiculously stronger, faster and more explosive that I knew for a fact I could work out for 10 years and I'd still never touch them.
You see the same thing in every sport.
There's a very small handful of genetic freaks who then compete at the higher levels and the vast majority suddenly realize that they're up against athletes that are even more freakish and now have to face the reality that they could never, ever compete with them without help.
And then you have the guys that are facing father time and want to extend their careers and paydays. The window for top line competition is pretty narrow in terms of the hours of punishment your body can take, especially when you're grappling or taking hits in actual fights.
The ones I find the most suspicious are the guys that have engaged in multiple wars, or who are fighting deep into their careers and still operate at a very high level but aren't highly technical, or who have very minor athletic backgrounds and are keeping up with fighters with very deep athletic backgrounds.
One thing I should note, the shifts in advanced legal treatment has changed the playing field substantially. Hyperbaric chambers, cryo chambers, massage, advanced nutrition, blood cell platelet injections and stem cell therapies are radically changing the sport in terms of recovery times. For the fighters that can afford it, it's increasingly becoming easier and easier to recover and train without the use of banned substances.
I do think we're going to see some serious changes in training practice. I believe that 2 a days will still happen, but I suspect the shift will increasingly be towards lower intensity workouts vs the all out wars in training that some camps seem to favor.
That and we'll start seeing fights where athletes gas sooner, lose mass, don't hit as hard, and suddenly don't seem as dominant in terms of strength versus their competitors. That and we may start seeing some of the fighters who have struggled a bit in the lower tiers suddenly start looking better and more competitive.
