UnderdogFantasy's weekly winners contest was first offered last year (2023). $3.5M prize fund with a max of 261,000 entries. (248,748 entries actually entered), with a 10.6% rake. For your $15 entry fee, you got a chance to win $20k every week. $205k was given out every week.

I reconstructed all quarter of a million lineups with their weeks 1-17 results.

Here's what I found:

**TL;DR:**

- 3 QB Stacks are optimal (Both 2QB/3QB stacks were +EV)
- If a RB/WR scored 6 points. 50% of the time that score would be used in the lineup's score. If a WR scored 10 points, that score would be used 90% of the time.
- Stacking byes can be extremely effective. In week 13 (6 bye week), Only 65% of the field, was able to construct a full roster (every position scored non-zero)
- Only 14 of the 32 stacks were +EV. Only 5 were extremely profitable (SF, MIA, HOU, DET, DAL)
- Elite WR/TE are over valued. This is seemingly a remenant of WeeklyWinners ADPs being derived from BBM. (Typically in best ball, Elite QB/TE value is compounded over the course of the regular season)
- Hero RB was the best strategy (this is probably skewed due to CMC starts)

# Player EV / Methodology:

# Positional Value:

In the above section, we looked at Player EV's. *i.e how valuable was a specific player over the course of a season in the WW format*. In this section we'll look at player scores by position instead to answer, **What weekly point thresholds should we care about for our players?** It is intuitive to the community that WeeklyWinners benefits players who's score spike more than normal BestBall formats. We'd prefer a WR who scores 30 points 1 week and 6 points the next vs. a WR who scores 18 in back to back weeks.

A standard Underdog Bestball lineup is made up of the following players:

- 1 QB
- 2 RB
- 3 WR
- 1 TE
- 1 FLEX (RB/WR/TE)

The lineup having asymmetric constraints based on position in addition to positional values being different. We perform a similar analysis to the Player EV one.

- For each player, we take their score and floor it. note their position, if the player was used and how much money that lineup made.
*Example:*DK Metcalf scored 18.4 points, his score was used in the lineup and the lineup cashed for $200- Data:
`{points: 18.0, position: WR, payout: 200, used: true}`

- Calculate the PnL and how often that score/position pair was used in the lineup:
