I don't just mean going 22-0 in one's league (as that happens all the time), I mean winning every game in a given season that they have played in all of the following:
- League Regular Season
- League Playoffs
- National Tournament (Cup)
- B3 or BBM
- Private Leagues
- Scrimmages
- Pickup Games
With 22 league RS games, 4 league playoff games if a sweep, assuming 2048 playoff slots per Cup for 11 Cup games, 7 B3/BBM qualifier stage games and 6 KO stage games, assuming 11 Private League games, two scrimmages (outside of Cup obligations), and a pickup game per week (14 games), a team should hypothetically be capable of going 77-0 in a season.
I've seen that even among the game's best teams have dropped a few games. Some examples I've found from recent previous B3 champs (yes, I am aware that all these teams play really hard competition, but if there really are no teams that have gone undefeated in this manner, is that simply the reason why?):
S72 dequestion - 55-7
S71 dequestion - 60-7
S70 Killers Reformed - 55-10
S69 Xeftilakos - 58-7
S68 Lancaster City - 46-9
S67 Sant Mateu - 53-12
S66 ESSEC - 62-4
