If there's a tie in a playoff matchup in a standard league, the higher seeded team will advance. This is also the default setting in League Manager leagues
NOTE: In League Manager leagues, the League Manager has the ultimate say on which teams advance using the "Edit Head to Head Schedule" option in LM Tools. Each league may establish their own tiebreaker system, with the League Manager, advancing the team that wins it.
NOTE: "Most Points from Bench" is an option only available for grandfathered Custom Leagues that used the tiebreaker rule in the past season
