Best Ball Buddy
Win your draft, pick by pick.
Best Ball Buddy is a Chrome extension that overlays a live, roster-aware Pick Score and real-time draft intel right onto your DraftKings or Underdog best ball board — no tab-switching, no spreadsheets.

See it in action
Recorded on a DraftKings draft. The same overlay — Pick Score, availability, stacks, byes, Top 3 — runs on Underdog too; see below for what differs.
Where it works
One subscription, both sites. Open a draft and the overlay appears — nothing to configure.
DraftKings
- Live Pick Score on every player, with the full factor breakdown
- Next-pick availability %, stacks, playoff matchups, bye clusters
- Portfolio exposure across all of your teams
- Queue any player straight from the rail
- Draft Grades for the whole room when the draft ends
Underdog
- Live Pick Score on every player, with the full factor breakdown
- Next-pick availability %, stacks, playoff matchups, bye clusters
- Top 3 board pinned above the player list, click-to-find from the rail
- Portfolio exposure across your Underdog teams, with pairing combos on hover
- Draft Grades when the room finishes — on an Underdog-style graded board
Turn it on once: click the Best Ball Buddy icon in Chrome and hit Enable Underdog support. Chrome asks for permission for Underdog's site, and that's it. Draft on DraftKings only? Nothing changes for you.
Grade the whole room, not just your team.
When your draft ends, Draft Grades replays every pick in the room through the same Pick Score model the overlay was running live — recreating the score each drafter saw at the moment they picked. Every team gets a capital-weighted 0–100 Draft Score and a rank, so you can see exactly where you finished against the rest of the room.
Every drafter, ranked
A capital-weighted Draft Score and rank for all 12 teams — with early / mid / late splits and the roster adjustments (stacks, bring-backs, draft-capital minimums) that moved each number.
Best and worst picks, called out
Every roster's best and worst pick flagged right on the board, plus who the model would have taken instead and the odds that player would've survived to their next turn.
Two lenses, one shareable board
Judge picks by today's rank and ADP, or by the values saved while the draft was live — then download the graded board as a PNG to post anywhere.
Draft Grades appears in the rail as soon as a room finishes — on DraftKings and Underdog (Underdog boards render in Underdog's own style). Grading by draft-time ADP uses a pool snapshot that Best Ball Buddy saves automatically while you draft.
Live Pick Score
Every available player gets a 0–100 score tuned to your roster — rankings vs. ADP, draft-capital targets, stacks, playoff bring-backs, bye spread, bench-pick awareness, and your position limits — recomputed on every pick. Tune the weights to your style.
How Pick Score works →Next-Pick Availability
See the odds each player makes it back to you before your next turn, so you know who to grab now and who can wait.
Best Pick Score, ranked
A live leaderboard of the best available players by Pick Score — with the Top 3 pinned right above the draft board, so your best pick is always one glance away.
Stacks & Playoff Matchups
Your live QB / run-it-back stacks and fantasy-playoff (Weeks 15–17) game stacks at a glance, with bring-back opportunities highlighted — right in the rail.
Portfolio Exposure & Combos
Drafting a lot of teams? See your exact exposure to every player across your whole portfolio — and which teammates you pair them with most — live on the board, on both DraftKings and Underdog.
Read the board at a glance
Rows tint by Pick Score, a marker shows how many picks until you're up, and bye-week clusters glow yellow or red — on both DraftKings and Underdog. Queue any player in one click on DraftKings.
