They are just making stupid mistakes. All the stuff I say are going to be from icebox today. Round 9, 7-1 Guard, TENZ is playing 410 and trent darts above 410, zombs is ready to flash (omen) but Tenz dry peaks into 2 people, and dies, zombs flashes the second he died. could have been more coordination there, zombs was also holding Tenz's right side so. They are many examples of Tenz just dry peeking and getting punished throughout the tournament.
2nd example same round I think, SEN somehow have a 4v2 advantage even after Tenzs mistake. Shaz drops from heaven to peek neT for no reason and dies, even though at the time 3v2, and zombs died 2 seconds ago so he couldnt have tried to trade, sick does the same thing after shaz dies. All just dry peeked neT's awp 1 by 1. Throughout the map SEN kept dry peeking and playing individually. Kept getting picked off of over aggression. The Guard just punished SENs mistakes, and against a well rounded team like the Guard, you are just going to get traded.
Everyone on SEN was spread out and isolated on their own island on CT side. Never did I see zombs flash for a teammate, or any creative plays from SEN. Here are some other mistakes without context to make things short. Tenz dry peeks through mid smoke alone and dies by omen on top of tube (5v5). Sick dry peeks 3 people mid alone and instantly dies (4v5). Tenz dry peeks belts from back site, while dapr is in his viper ult (5v5). Sayaplayer awped to counter Tenzs over peeking and it worked perfectly, Saya often picked off Tenz when it was a 5v5 when Tenz overpeeked.
I think also the lack of kayo in their comps really shows, they always get overwhelmed on sites. On bind they didnt play flashes, and it really showed how they were struggling to get out of
hooka and short.
TLDR: SEN are just making stupid mistakes, lack of communication, isolated, not util combos, overpeeking
