Use Your Bonus Code To Play On Underdog Tonight
Underdog lets you build pick’em slips where you stack individual props to create a coherent narrative.
Example narrative for tonight: “Miami controls the game with Achane, keeps Pittsburgh’s offense off the field, and stays competitive.”
How that builds on a pick’em slip:
- De’Von Achane HIGHER 80.5 rush yards
- Jaylen Warren LOWER 47.5 rush yards
- Jaylen Waddle HIGHER 63.5 receiving yards
That’s a coherent narrative, not random props. Each prop feeds the same story.
De’Von Achane HIGHER 80.5 Rush Yards
This is the anchor prop for any Dolphins pick’em slip tonight.
Achane has rushed for 90+ yards in 4 straight games during Miami’s win streak. Pittsburgh’s run defense ranks 20th in the NFL (127.9 yards per game allowed).
The real kicker: T.J. Watt—Pittsburgh’s best pass rusher—is OUT. Without him on the edge, Achane gets cleaner running lanes on outside zone runs. He should see 18-22 carries and easily clear 80.5 yards.
Other Achane props on Underdog:
- HIGHER 27.5 receiving yards (hits if Miami uses him in passing game)
- HIGHER 110.5 rush + rec yards (stacks with rushing total)
Jaylen Waddle HIGHER 63.5 Receiving Yards
This one’s worth monitoring the pregame report—Waddle is listed as questionable with a calf injury. But if he plays, this prop has serious value.
Waddle is Miami’s elite slot weapon. Pittsburgh’s secondary ranks 18th in pass defense. Even in a run-heavy game, Waddle finds ways to produce on quick slants and crossers that exploit zone coverage.
Other Waddle props on Underdog:
- HIGHER 23.5 longest reception (one explosive play gets you there)
- 7.5 targets (if healthy, he’s Tua’s safety valve)
Underdog Value: If Waddle plays, stack him HIGHER 63.5 with Achane HIGHER 80.5 for “Miami’s offensive weapons hit their averages” pick’em slip.
Jaylen Warren LOWER 47.5 Rush Yards
Here’s a contrarian angle: Jaylen Warren is Pittsburgh’s 1A back, and if Miami controls the clock with Achane, Warren won’t see enough volume to hit 47.5 rushing yards.
Warren’s season average is around 40-45 rushing yards per game, so this line feels slightly inflated. If Miami’s defense forces Pittsburgh into passing situations, Warren’s carries get limited.
DK Metcalf HIGHER 54.5 Receiving Yards
Metcalf has been wildly inconsistent (502 yards through 9 games), but last week he went off for 121 receiving yards on deep balls against Baltimore. If Rodgers trusts him again Monday night, this clears easily.
Against a Miami secondary that ranks 24th in scoring defense, Metcalf’s ceiling is absurd if Rodgers has time. If you believe this connection is real between Rodgers and Metcalf, you could have some fun by using our Underdog Bonus Code (PROPS).
Other Metcalf props on Underdog:
- HIGHER 24.5 longest reception (one deep shot gets you there)
- 10.25 fantasy points (TD upside if Rodgers connects)
