Result =/= titles
a great result for a team like BIG for example, is getting to the quarters of a big LAN event.
Fnatic has been nowhere near the level they are at right now since olofmeister got injured, and the only large change they've made in the last 6 months that resulted in this now large uptick in power was adding in Golden.
Golden took fnatic from a bottom of the top 10 to winning 2 substantial tournaments in 1 month. In one of them they beat the current HLTV top rated team twice in series, in the other they beat the reigning major champions in a bo1.
It's not just Golden coming in, you forget that the "carry performance" coming from flusha and KRiMZ is because they have given Golden 100% control over their team. They said so in an interview. Paraphrasing here but:
"We don't care that he has less experience, he doesn't need to worry about that with us, we will give Golden full control of our team"
So the incredibly good performances and victories are most likely a direct cause of that. Golden taking over.
If you only look at stats and say Golden's useless because he doesn't frag, you have no clue what he's actually doing in the team.
