How are you gonna clutch if you're the only CT alive, you're heaven with an awp and your team has no money. I mean, he's not S1mple and this is not matchmaking, he had to save.
Problem was on tactics, Broky had 0 impact on Nuke because he was wasted using an awp on heaven and being a supporter of olof on ramp and niko outside, so he was running like a chicken with no head from one side to the other. Niko plays really well outside, but which other T1 team has no AWP outside of Nuke? There was a couple of times where he ended up being in top of hut with the awp, it has no sense.
Ofc he missed the shot on the 2vs2 that was needed so Olof could get out of vents, but it's the same, he was on heaven without knowing where the other 2 were on site, so he needed to get out, spot them and kill one of them hoping Olof flash worked. Sure it's doable, but he missed and the rest is history. I don't think is his fault.
