Pressure. I think it being Jinggg's last game got into their heads, and they made a lot of mistakes on lotus and split. Honestly lotus was so winnable, they almost won the bonus ffs. As for split, they blew a 8-4 lead and played so uncoordinated on CT side.
All in all, EG had less pressure on them and so they made fewer mistakes. PRX let the pressure get to them, but I can't even be mad because how do you not feel pressure in their situation? I blame national service for their loss. If Jinggg were not leaving after champs, then PRX would not be so pressured man.
