Without lagging, LG could have won the match.
Genuinely though, I think there wasn't much chance
From what I saw, aproto had to peek into both Zekken and Ayrin's view to be able to kill them, and he doesn't even know where Zekken is.
Even if he picked off Ayrin, there will be NO way he can flick over and get Zekken at the box
If he killed Zekken first, Ayrin would've turned around and been able to trade the kill off anyways
Also, there was literally 6 seconds left lol
