Purdue vs Iowa Best Pick, Prediction and Odds

Our number has Iowa by 13.7. At +17.5, take Purdue.

No. 16 Iowa is a 17.5-point favorite over Purdue at DraftKings. Our number is Iowa by 13.7. The gap is 3.8 points on Purdue’s side, and the threshold for a bet is 3.

The prices and what they say

Purdue Boilermakers at Iowa Hawkeyes kicks off Saturday 14 November at 7:30 PM ET, at Kinnick Stadium in Iowa City. DraftKings has Iowa -17.5 at -108 and Purdue +17.5 at -112, read 13 November 2026 at 00:37 UTC. Iowa opened at -16.5.

The moneyline is Iowa -950 and Purdue +625. A book’s margin is the extra it builds in so that the two prices add to more than 100%. With the margin removed, those prices give Iowa an 86.8% chance to win and Purdue 13.2%. ESPN’s FPI has it at 87% and 13%.

How 13.7 is reached

Our number is half the difference between the home team’s average margin at home and the visitor’s average margin on the road, against FBS teams only, over 2025 and 2026 together. Bowl and playoff games are played at neutral sites, so they are left out.

Iowa is 7-3 at home against FBS teams over that span, winning by 13.1 points a game. Purdue is 1-7 on the road against FBS teams, losing by 14.2 a game. Half the difference between those two averages is 13.7 points in Iowa’s favor.

The rule bets a side when it and the spread are at least 3 points apart. The spread is 17.5, which puts the gap at 3.8. Both samples clear the 4-game minimum: Iowa’s has 10 games, Purdue’s 8.

This season so far

Iowa is 7-2, 4-2 in the Big Ten, and has won two straight, most recently 24-10 at Northwestern on 7 November. Against FBS teams it is 6-2 with a margin of +10.6 a game. Across all nine games it has scored 27.8 points a game and allowed 12.2.

Purdue is 3-6, 2-4 in the Big Ten, and has lost three straight. The latest was a 34-29 home loss to Maryland on 7 November. Against FBS teams it is 2-6 with a margin of -6.4 a game, and across all nine games it has scored 29.4 and allowed 32.3.

None of these season figures is in our number. The method reads only the two venue splits.

Iowa at home, Purdue on the road

Iowa’s home games against FBS teams this season are a 40-0 win over Northern Illinois, a 16-13 win over Iowa State, a 31-14 loss to Ohio State on 3 October and a 30-0 win over Wisconsin. The 55-0 win over Northern Iowa is not counted, because Northern Iowa is outside the FBS. The rest of the 10-game home sample comes from 2025, when Iowa went 5-2 at home in all games.

Purdue’s road games against FBS teams this season are a 52-38 loss at UCLA, a 24-17 win at Illinois on 3 October and a 31-17 loss at Penn State. In 2025 Purdue was 0-5 on the road. The Illinois game is its one road win against an FBS team across both seasons.

The halves the method leaves out read the same way. Iowa on the road this season won 20-19 at Michigan and 41-24 at Washington, and lost 13-10 at Minnesota. Purdue is 2-4 at home this season, including a 49-10 loss to Notre Dame.

The season around it

The two teams share two 2026 opponents, and the results split. Iowa won 41-24 at Washington; Purdue lost 38-26 at home to Washington. Iowa lost 13-10 at Minnesota; Purdue beat Minnesota 41-13 at home. Both of Purdue’s results are home games, so neither is in our number.

Iowa went 9-4 in 2025 with an average margin of +13.2, and beat Vanderbilt 34-27 on 31 December 2025 at a neutral site. That bowl game is outside the method. Purdue went 2-10 at -13.1 a game, 1-10 against FBS teams, with no postseason.

Purdue and Iowa have not met in 2025 or 2026, so no meeting enters the number.

Pick: Purdue +17.5

Purdue +17.5 at -112, DraftKings, read 13 November 2026 at 00:37 UTC. The gap is 3.8 points against a 3-point threshold.

Iowa opened at -16.5, so Purdue opened at +16.5. That opening price would not have been a bet under the rule. The bet exists at the current line.

What kills the bet

The line. Purdue is a bet down to +16.7. Below that the gap falls under 3 and the call becomes no bet. Iowa would need to be -10.7 or shorter to be the bet.

The risk is this season. Iowa has allowed 12.2 points a game across nine games, and its FBS margin of +10.6 comes with a defense that shut out Northern Illinois and Wisconsin at home. Our number trusts two seasons of venue splits over that form. The 0.8 points of margin above the threshold is a thin cushion.

No absence enters this number: the ESPN game page, read 13 November 2026 at 00:37 UTC, gave no injury list. Check the lineups before you bet.

The total

The total is 47.5, up from 45.5 at the open. The over is -112 and the under -108 at DraftKings.

Against FBS teams across 2025 and 2026, Iowa’s games went over in 6 of 20 and Purdue’s in 13 of 19. This season Iowa’s eight FBS games produced 40, 29, 39, 45, 65, 23, 30 and 34 points. Purdue’s produced 74, 90, 59, 41, 54, 64, 48 and 63.

No bet on the total at 47.5. Our method stakes the spread only, and the two teams’ counts point in opposite directions.
