Although Liquid (or any other team ever, for that matter) stands little chance of beating 87-0, the fact that tournaments had fewer Bo3s/Bo5s during NiP’s heyday means that their record on that front is more achievable. Liquid currently stands at 20 consecutive Bo3s/Bo5s won, starting after they lost to Vitality at cs_summit 4, while NiP, during their 87-0 streak, won 25 straight.
Astralis, Fnatic, EnVyUs, and the Brazilians all maxed out at 9. (Fnatic had an 8 match streak that ended with that boost; if it had been allowed, and they went on to win DreamHack Winter 2014, they would have hit 13). Virtus.pro won 10 in a row soon after NiP’s era, while NaVi are the only team to even come close to Liquid’s current streak with a 16 match run during the summer of last year.
(Note that although I checked every team I thought would have a streak like this, it’s entirely possible that one fell through the cracks. Only teams with a streak at 9 or longer are included – I also checked Cloud9 and FaZe, but they didn’t have any super-long streaks. Maybe a French team, I can barely wrap my head around their shuffles. However, I’m also fairly sure that if a team managed a streak longer than 25, I’d remember them for other reasons.)
Going 3-0 and winning the major would put Liquid at 24; the clincher would be the winners’ match in the group stage at ESL One New York.
TL;DR: Liquid need 6 more Bo3s/Bo5s to beat NiPs record for LAN series wins in a row.
