They lost 1 seeding match to G2 and 1 map in a game that didn't matter at all. SEN beat also G2 earlier when it mattered more.
SEN have also played and scrimed envy a bunch before since they are from the same region.
I believe the upset is possible but so many people think it will happen and i just don't think its as likely as people say it is.
If you have a reason why please let me know and i would love to discuss
also please don't comment "delusional sen fan cope harder" or some shit, i watch more EU val than NA i don't really like SEN that much.
