Team Builder Tutorial
The Underdog Fantasy Best Ball Team Builder is an interactive draft-board fueled by the latest ADP data from on-going Underdog drafts. It is designed for build discovery and experimentation as a pre-draft planning tool and live-draft companion.
Here's how it works:
1.1 — Choosing a draft slot filters the board to the top stacks reachable from the chosen draft position based on current Underdog ADPs.
Learn more about the data model
1.2 — The stacking targets box provides more information on the filtered teams including the reachability status of their most stacked players:
- Green: Best 2-Player Stack (excl. RBs)
- Yellow: Limited Reach (ADP conflict)
- Grey: Out of reach
Teams are default ranked on the projected value of their best reachable 2-Player stack.
2.1 — Use the team filters to highlight only the teams you want to target.
For example, planning a build around a Week 17 DAL-WAS game stack from Draft Slot 5.
2.2 — Only players on your selected teams will be highlighted on the draft board.
The green highlight indicates your draft position by round
3.1 — Selecting a player opens a team window with ADP, reachability, and point projection detail.
- The highlighted player can be Added or Removed from your build here
- The Fade checkbox will dim the player on the draft board
3.2 — The stacking targets box will update to reflect stacks and correlation in your build as players are added or removed.
- Rostered players are filled in green
- Highlighted teams indicate # of players in your build
Points shown represent projected points rostered
4.1 — The expandable Build panel shows more detail across 3 tabs:
All players
Distribution across teams
Weeks 15–17 correlation
