paper rex played like paper rex selling free rounds but they didn't "get lucky with amazing timings", they are genuinely that fucking locked. if you go through their vods you can see their minds are running at a million miles per minute, and their decision making (good or bad) is so fast that no team is every truly ready for it. for jinggg's 3k on split, you can go back and see the thought process for every move he makes, and he does it so quickly that NRG aren't ready. it's the same reason f0rsaken actually pulled off the ace, after every kill he knew what he wanted to do next.
sorry for being on the rant
TL;DR: "god timings" don't win games, paper rex is just like that
