For first-time prop bettors who want to know why a pick is a pick — not just whether to tail it.
ET Parlays (The Lab) is a sports-betting research and decision-support tool for newer bettors — it grades player props with the reasoning shown and checks your bet slip leg by leg before you place it. You bet wherever you already bet; ET is the research desk.
Not just a pick — you see the tier (S/A/B/C), the stats behind it, and exactly why it's a play.

The Method
Three principles. One lab.
We don't tweak the model when the slate has a bad night. The doctrine is the product.
01
Tier grades, not tip sheets.
Every prop scored S/A/B/C from the model. You see the math. A B stays a B — we don't repackage it with marketing copy.
02
Trust and verify.
A ranked Top 10 if you want a fast read. A sortable Board if you want to scan the slate yourself. Both, every day, every sport.
03
Bring your own book.
Slip Check runs any slip against the ET database — see exactly how each player grades on today's slate. Book-agnostic by design: bet where you want, check the read here first.
Coverage
Six leagues. Done right.
We don't pad the marketing with sports we haven't built yet. What's listed is what's live.
MLB
Full slate, every prop tiered. Read against the matchup before first pitch.
NBA
Same depth as MLB. Every prop tiered, every matchup read before tip-off.
WNBA
Full slate coverage with the same grading depth as NBA. Tiered props on every game.
WTAATP
Tennis
Grand Slams with serve-model predictions and same-match correlation surface — the only tool modeling joint leg outcomes.
KBONPB
World Baseball
KBO + NPB. Props nowhere else will touch. Built for the gaps when domestic markets sleep.
NFL
