Several franchise cricket leagues end with four teams but do not play straight semi-finals. The structure gives the top two an extra life, and that changes the whole regular season.
The ladder is not a bracket
In a conventional bracket the first-placed team plays the fourth, and one defeat ends the season regardless of where a team finished.
A ladder instead pairs first against second in one match, with the winner going directly to the final. The loser drops into a second match rather than out of the competition.
Third and fourth meet in an elimination game, and its winner faces the team that lost the earlier qualifier. Only then is the second finalist decided.
The advantage is a second chance, not a bye
Teams finishing first or second must lose twice to be eliminated. Teams finishing third or fourth must lose once.
That is a substantial reward, and it is granted for regular-season performance rather than for a single good night. Leagues adopting the ladder are explicitly weighting the long season more heavily.
It also means the top seed's reward is insurance rather than an easier opponent, which is a different kind of advantage from a bracket's.
It changes what teams play for in the closing weeks
Under a bracket, the gap between second and third is modest. Under a ladder it is the difference between one defeat and two.
Late-season matches therefore carry weight even between teams already qualified, because position within the four determines the format of survival.
Coaches manage rest and rotation against that. Resting players to secure a top-two finish is a defensible trade in a way that resting for third is not.
The format produces more meaningful matches
A four-team knockout requires three matches. A ladder requires four, and all of them involve teams with something live at stake.
That extra fixture has commercial value, which is part of why the format spread. It also gives the competition a longer finish without extending the regular season.
Broadcast schedules are built around this, since a fixed number of playoff matches on known dates is easier to sell than a variable bracket.
The trade-off is a longer path for the lower seeds
A team finishing third or fourth must win three matches to lift the trophy, often in quick succession and sometimes across cities.
Critics argue this makes late qualification close to worthless. Defenders reply that this is the point, and that a league table should mean something in a knockout.
Either way the design is coherent. The ladder states plainly that the regular season is the competition and the playoff is its settlement.
