Testing WhatIfSports League (TWISL)
Section 1: LEAGUE PHILOSOPHY
The TWISL is a multi-season league in which each season is designed to help us better understand the SLB algorithm. Each season will be different, and owners may come and go as they choose depending on their interest level in each season’s theme. There is no expectation that owners commit to multiple seasons.
However, it is important to know that this league is designed first and foremost to create better understanding of how SLB really works. This means that each season will involve various roster constraints, or theme rules, and that occasionally these may result in one or more teams being at a disadvantage compared to others. While I will do my best to construct rules that will allow each team to be as competitive as possible within the construct of each season, that will be a
secondary consideration. If you signup to participate in any season of this league, please do so with the understanding that the playing field may not be level.
Section 2: LEAGUE STRUCTURE AND WIS RULES
TWISL is intended to be a 24-team league each season. If we do not have sufficient owners to reach 24 teams within a reasonable amount of time after the first theme posting (typically 7-10 days) then we will use a smaller league (16 or 20 teams, depending on how many owners signup). This will not be put to a vote. Please only signup if you are willing to play in any format (16, 20, 24 teams).
While the exact WIS rules for each season may vary, in general each season will have an 80M cap, no DH, no AAA, no WW, no trading, with injuries ON. Clones may or may not be allowed depending on the specific theme idea we are playing each season.
Section 3: THEME IDEAS
TWISL will last as long as there are interesting questions about SLB for us to test in a workable theme that will attract owners. Some ideas for specific themes will be:
- What is the effect of pitcher K rate on range (plus plays)? THIS WAS THE THEME FOR SEASONS 1 AND 2
- How much does fatigue impact hitter performance?
- How much does fatigue impact pitcher performance?
- What do park factors really mean? How much additional offense is generated by a park that is +1 or +2 for 1B/2B/3B/HR compared to a neutral or negative park?
- How do the park factors work in combination? Will more triples be hit in a park that is +1 or hits and +1 for triples, or in a park that is -3 for hits and +3 for triples? THIS IS THE THEME FOR SEASON 3.
- How important are manager settings? If you set all of your base stealers to 4 or 5, how many more SB attempts will they have compared to setting them to 1, 2, or 3?
- What impact do the H&R and baserunning aggressive settings have?
- How do the LH and RH specialist relief settings work? What is the impact of setting all your short relievers to LHS/RHS rather than (say) Setup A/B?
- What is the impact of range on double plays?
- There are no doubt many more, and owners are encouraged to suggest their own ideas for us to test. The only condition is that it has to be something around which we can design a workable set of league rules.
Note that to make the tests as reliable as possible, for most of the above we will need to put significant restrictions on roster composition. For example, if we are testing the effect of baserunning aggressiveness, we will likely want each team to have exactly the same set of offensive players (or at least the same starting lineup). Otherwise there are significant confounding variables that will dilute our ability to understand the specific effect we are looking for.
