USADA isn't to blame for her shit striking and even worse defense. She always got tagged rushing into the clinch, she finally ran into chicks as strong and big as her who knows how to strike way better than here, and most importantly aren't scared of her.
hypothetically though, coming off a program can have a huge impact on your confidence which in turn effects all aspects of your fight game.
Weve seen it in countless sports when someone who has previously been on a program comes back "clean". not just physical strength goes, stamina etc, but the confidence, aggression, you question your ability more and so dont attack the way you would do previously etc.
So lets imagine, hypothetically, youve been on PED's of some form your entire career. Might not even be anything major, might just be a lil' something to help you focus or concentrate,might be a lil'something to make the weight cut easier. Then take away that "lil' something" that youve been, maybe not dependant on, but have come to rely on to a degree for maybe ten years. Of course your confidence takes a hit.
No different to if someone has fought their entire career with a certain coach, and suddenly that coach is taken away.
people really underestimate the mental impact of ped's, maybe not in taking them, but the mental impact when they are taken away.
weve seen it in countless fighters over the last 18 months.. spot the guy who normally steams forward, suddenly more cagey, more unsure of his cardio, etc etc
