Template:BracketMatchPlayers/doc
From QWiki
This is a subtemplate that you will never use directly.
It only renders the header row of the popups.
It handles Player/team1 and Player/team1flag to the left, and Player/team2 + Player/team2flag to the right.
After it, {{BracketMatchSummary}} renders all rows below, like date, maps, scores, overtime, etc.
BracketMatchPlayers2
For 2on2 contexts, used only by certain brackets ending with '2on2' , where you want both teamname and teamlineups shown in the header, see {{BracketMatchPlayers2}}.
It handles team1, team1flag and team1lineup to the left, and team2, team2flag and team2lineup to the right.
