Hey boss, cool idea for some articles. I actually think highly of a great deal of Pavel's contributions, although it's a very mixed bag to be clear. This may be a bit rambling, but...
I first encountered Pavel's writing in (maybe '99) PLUSA, in the original Smolov-Feduleyev squat program article. The whole approach was far different from the Western periodization style programs that I typically saw there, and it pretty well summarizes a lot of what I liked about his early stuff: it was detailed, it was clearly presented, and it was based on empirically-tested Soviet sports science instead of bro-knowledge from the latest star lifter.
He kept to that basic formula in Power to the People, which remains an excellent primer for people interested in strength training. Even just recently I was doing a program very similar to it: press, pull, curls, just like in the book, for frequent low-volume workouts and getting great results. His ability to cut through the haze of choices facing a trainee and be like, "do this" and measure your results, is incredibly useful in this age of information overload is invaluable.
From there, his other notable works to me are Relax into Stretch and Russian Kettlebell Challenge. RIS remains my go to stretching book, and if I'm struggling in some area I will virtually always consult that book and use it's basic principles to address the problem. There's a reason why Louie Simmons was crazy about this book, and to be honest, if Pavel is a true expert at anything, it's flexibility training.
Finally, RKC and all the dogshit that came after it. Fedorenko may be the guy who introduced real, Russian GS-style training to the USA, but honestly nobody gives a fuck. Everyone knows it was Pavel who put KBs in the hands of a billion bros. He made them available, but more to the point, he got people excited about the idea. That's something really rare: the ability to recognize untapped value, generate enthusiasm for it, and then market it. Only a few people, guys like Arthur Jones, can do it. Pavel did it in spades. Now, anybody who looks at the original RKC video can see that Pavel is not the master of any fucking sport at all. He's terrible. I mean it. But he did have the basic idea that training a variety of high-tension and ballistic lifts with kettlebells could make almost anybody stronger and more athletic, and he was able to pass that on to many, many other people. Kettlebell training has been a huge boon to my training over the years, and I credit him with that.
Final, final codicil to all of this is that Pavel's greatest strength is his ability and willingness to keep learning. I think that he did not come to the US as a master coach, he made himself into one here, by associating himself with people who really know what the fuck they are doing and being willing to draw on these strands and tie them together.
