Its happens in CSGO too, tho.
Is Jame supposed to be a bad player? You relying your analysis in a meme? What you even talking about?
Look at gla1ve (best IGL all time) bold prediction on Jame back in 2018. Guy went top 10 and 20 last two years.

Not constantly in grand finals, but is always there in playoffs and being in top 15 at least in the ranking. Tier 1 CSGO is not that short like valorant since the game has 10 years and knowledge spreaded like crazy (both skill floor and ceilling hightened with this). There are no fools in CSGO anymore. Tier 2 and 3 actually know how to play the game. But they winning a match against a T1 team is not like the ceilling is lower or smth. Bad/good days happens with everyone. It would be if they get trophies randomly from tournaments full of t1 teams.
