Don’t let the rankings fool you; there is a massive gulf between these two 8-1 squads. Purdue is firing on all cylinders, and a rebounding-deficient Iowa team is walking into a buzzsaw at Mackey Arena. Read on for how Bash is playing this and get his ATS pick.
The Setup: Iowa at Purdue
The Boilermakers host the Hawkeyes on Wednesday night at Mackey Arena and on the surface, this looks like a classic Big Ten rock fight between two 8-1 teams. But there is more to it – when you dig into the collegebasketballdata.com efficiency numbers, this isn’t the coin-flip matchup the identical records suggest. Purdue ranks 11th nationally in adjusted net efficiency at +23.4, while Iowa checks in at 34th with a +16.2 mark. That’s a seven-point gap in efficiency, which in a normal-paced game translates almost directly to expected margin of victory. The Boilermakers are also playing at home, where they’ve been absolutely dominant, and they’re catching an Iowa team that just dropped back-to-back conference games to Illinois and Minnesota. Let me walk you through why this double-digit spread isn’t just justified – it might actually be light.

Why This Number Makes Sense
The efficiency gap tells the entire story here. Purdue’s adjusted offensive efficiency sits at 119.2, ranking 27th nationally according to collegebasketballdata.com. That’s excellent, but what really separates these teams is the defensive end. The Boilermakers check in at 100.4 adjusted defensive efficiency (42nd nationally), while Iowa’s defensive rating of 103.0 ranks just 85th. That three-point defensive gap might not sound massive, but here’s what it means in practical terms: Purdue defends at an elite level, while Iowa is merely above average.
Now flip to the offensive side. Purdue’s adjusted offensive efficiency of 123.8 ranks 7th in the entire country – that’s not just good, it’s elite. Iowa’s 119.2 mark is solid at 27th, but we’re talking about a four-and-a-half point gap in offensive efficiency. Do that math over 70 possessions in a game, and you’re looking at a natural margin in the 10-12 point range before we even factor in home court advantage.
Here’s the matchup that seals it for me: Purdue ranks 10th nationally in three-point percentage at 40.2%, while Iowa allows opponents to shoot 31.5% from deep (133rd nationally). The Boilermakers also rank 8th in assists per game at 20.2, meaning they’re getting quality looks within their offensive system. When an elite three-point shooting team faces a defense that doesn’t pressure the perimeter particularly well, you get blowouts.
Iowa’s Situation
The Hawkeyes come in with an impressive 8-1 record, but those two recent conference losses expose some real problems. Iowa plays at a glacial pace – 58.3 possessions per game ranks 358th nationally out of 362 teams. That’s not just slow, it’s suffocating. They want to grind you down, limit possessions, and win ugly. The problem? When you only get 58-60 possessions in a game, every single possession matters exponentially more, and Iowa’s offensive rating of 137.0 (12th) suggests they’re incredibly efficient when they execute.
Bennett Stirtz leads the way at 18.8 points per game, ranking 63rd nationally in scoring. He’s a legitimate weapon. But here’s Iowa’s fatal flaw: they rank 353rd in rebounds per game at just 30.0, and their offensive rebounding percentage of 28.9% ranks 267th. That’s catastrophic against a Purdue team that grabs 40.0 rebounds per game (65th) and posts a 33.9% offensive rebounding rate (92nd). The Boilermakers will dominate the glass, and in a low-possession game, those extra opportunities become backbreakers.
Iowa’s defense has been solid – they allow just 62.6 points per game (12th nationally) – but that number is heavily influenced by their snail’s pace. Their adjusted defensive efficiency of 103.0 tells the real story: they’re good, not great, when you account for tempo.
Purdue’s Situation
The Boilermakers are rolling, winners of five straight including an impressive 88-60 demolition of Auburn and an 89-73 road win at Wisconsin. This is a team firing on all cylinders. Braden Smith runs the show with 8.7 assists per game, ranking 2nd nationally – that’s not just a stat, it’s why Purdue’s offensive efficiency is so elite. He’s getting everyone involved, creating quality looks, and making the defense rotate.
Trey Kaufman-Renn gives them 13.9 points and 10.7 rebounds per game (11th nationally in rebounding), providing the interior presence that will absolutely feast against Iowa’s undersized lineup. Fletcher Loyer adds 14.4 points with that deadly three-point stroke, and Oscar Cluff chips in 11.1 points with 8.9 boards (49th nationally). This is a balanced, deep roster with multiple ways to beat you.
Here’s why this line makes sense: Purdue’s 123.8 adjusted offensive efficiency (7th) means they’ll score efficiently regardless of Iowa’s pace. Even if the Hawkeyes slow it down to 60 possessions, Purdue’s offensive system is too polished to be disrupted. They rank 100th in free throw percentage at 74.2%, so they’ll convert at the line when Iowa starts fouling late.
The home court factor at Mackey Arena can’t be overstated. Purdue’s been dominant there historically, and playing in front of that crowd with their offensive rhythm clicking? Iowa’s in trouble.
The Matchup: Where This Gets Decided
This game lives and dies on the rebounding battle and three-point shooting. Purdue holds a massive 10-rebound-per-game advantage (40.0 to 30.0), and their offensive rebounding rate is five percentage points better. In a 60-possession game, that’s 3-4 extra possessions for the Boilermakers. If each possession is worth roughly 1.2 points based on their offensive efficiency, that’s an automatic 4-5 point swing just from controlling the glass.
The three-point matchup is even more lopsided. Purdue shoots 40.2% from deep (10th nationally) while Iowa allows 31.5% (133rd). Meanwhile, Iowa shoots 37.7% from three (41st) against a Purdue defense that holds opponents to 32.0% (149th). Purdue has the advantage on both ends of the three-point line. That’s a 15-point swing right there when you factor in volume and efficiency.
I keep coming back to those pace numbers because they’re just too extreme to ignore. Iowa wants 58 possessions; Purdue prefers 67. The home team typically dictates pace, which means we’re looking at somewhere around 63-65 possessions. That favors Purdue’s style more than Iowa’s grind-it-out approach.
The head-to-head history shows Purdue winning the last three meetings, including a 90-81 victory last February and an 87-68 beatdown in December 2023. The Boilermakers know how to attack Iowa’s defensive scheme, and Matt Painter has owned Fran McCaffery in recent years.
My Play
The Pick: Purdue -10.5 (3 units)
I’ve considered Iowa’s ability to slow the game down and keep it close, but the efficiency gap is still too massive to ignore. Purdue ranks 11th in adjusted net efficiency; Iowa sits at 34th. That’s not a small gap – it’s the difference between a legitimate national title contender and a solid NCAA tournament team. Add in Purdue’s rebounding dominance, their elite three-point shooting against Iowa’s vulnerable perimeter defense, and the home court advantage at Mackey Arena, and I see a comfortable double-digit victory.
The main risk here is if Iowa executes their pace-control gameplan perfectly and keeps possessions in the mid-50s. In that scenario, variance increases and anything can happen. But Purdue’s offensive system is too refined, too efficient, and too balanced to be slowed down enough to keep this within single digits.
I’m projecting Purdue 78, Iowa 65. The Boilermakers cover the 10.5-point spread by controlling the glass, knocking down threes, and slowly pulling away in the second half as Iowa’s lack of depth and rebounding catches up to them. This is a statement game for Purdue in Big Ten play, and they make it loud and clear.
