Have they ever lost a BO5?
well, TSM v SEN in FAZE Invitationals was kind of mickey, since TSM got a 1 map adv. because Bo5's weren't fully fleshed out.
edit: NA Chal 2 Stage 1 was also similar with the map adv. BS, but NV would've been up 2-0 regardless, not to likely to have a rev. sweep
G2 are notoriously weak in BO5s and SEN are historically strong in BO5s. Guess we all know what that means.
Last BO5 they won was against M80 when they were still the guard
After that:
0-3 100T
0-3 TH
1-3 LEV
As for SEN (post-franchise):
3-0 against PRX afreeca TV
3-2 LOUD 2024 kickoff finals
3-1 PRX madrid lower finalfs
3-2 GENG
3-1 MIBR
oh yea
so they're 1-3 while SEN is 4-0 (if we dont count the offseason one)
