## Episode Overview

Mark is back on his home turf — a Saturday-night live broadcast ahead of the Iowa Corn 350, his first Saturday-night show "in a while" after a stretch of Sunday-morning broadcasts, a failed live attempt in Florida during the Indy weekend, and a week off. The mood is loose and glad to be back, and the whole episode is built around one central task: walking through the full 36-car field on the racingdraft.com DK Calculator and Optimizer to build a DraftKings storyline for a 350-lap, 306-mile race with 246 dominator points on the table.

The dominant theme of the night is that this is shaping up as a Penske-heavy race. Ryan Blaney sits on the pole after the most practice laps of anyone in the field (93) and looks capable of checking out; Joey Logano qualified third and, per the broadcast, looked like he was on "a Sunday drive" in qualifying while everyone else fought their cars. Mark's read is that Blaney and Logano are the two most likely dominators, and that reality cascades through every other lineup decision because it caps how many laps anyone else can realistically lead. Meanwhile Hendrick/Chevy (Larson, Byron, Elliott, Bowman) and 23XI (Reddick, Wallace, Herbst) largely stubbed their toes in practice and qualifying, and a cluster of contenders — Keselowski (wrecked in qualifying, going to a backup), Briscoe and Hamlin (brake issues), Elliott (spun into the wall), and Preece (failed inspection twice) — are all headed to the rear.

Mark also spends real time teaching the mechanics of his tools: how the DK Calculator pulls qualifying spots plus track-and-comparison history (Iowa has only two Cup races, so he blends in North Wilkesboro, Phoenix, and Richmond), how his "power rank" algorithm weights five races at the track, ten similar-track races, and a five-race oval trend, and how the Optimizer lets you set min/max exposures and excludes to mass-build lineups. His repeated warning: this is going to be a genuinely tough build because the field is extremely top-heavy, with almost nothing playable in the cheap tier.

Track Setup, Format & Broadcast

The Iowa Corn 350 is 350 laps / 306 miles: Stage 1 is 70 laps, Stage 2 is another 70, then a full 140-lap run to the finish. There are 246 dominator points available — big, but short of the ~500 you'd get at a Bristol or Martinsville — so Mark is building around one clear dominator plus a secondary, then filling with place-differential plays coming from the back. Coverage flips back to USA Network with the NBC crew, and Mark is happy to have Leigh Diffey back on the call plus Jeff Burton in the booth (a chat member is lukewarm on Burton; Mark defends him but agrees Dale Jr. is the gold standard).

Mark leans on his track comps hard: Iowa's banking and race length are "almost identical" to Richmond (which is up next week), and he notes Iowa was designed with input from Rusty Wallace using Richmond as a template. He also comps to North Wilkesboro (three weeks ago), Phoenix, and Martinsville. Iowa is notably bumpy — bumps entering and mid-turn one, in turn two, off the exit of two, and through three and four — and the Next Gen car "does not like bumps," which is exactly what bit Brad Keselowski on lap two of his qualifying run.

The Optimal-Lineup Benchmarks

Mark frames the whole build around what a driver needs to score to be "optimal" at his salary. His thresholds for this race length: ~65 points for the expensive tier ($9,500+), ~60 from roughly $7,500–$9,500, ~55 from $6,500–$7,500, ~50 above $6,000, and roughly 45–50 for the cheapest arms, with 33 points as the floor for a top-15 driver. History backs the "start up front, stay up front" script: William Byron won the optimal here last year leading 141 of 350 laps (95.65 pts), and Ryan Blaney made the 2024 inaugural optimal starting second and leading 201 laps. That's why Mark hunts for two drivers starting and finishing top-five to top-ten as his dominator core, then three coming from the rear.

## The Penske Storyline

The night's central thesis: build the majority of lineups around Penske speed. Blaney (pole, fastest, previous Iowa winner) and Logano (qualified third, effortless-looking qualifying lap, North Wilkesboro dominator two weeks back) headline. Mark's practical wrinkle is that he doesn't love pairing Blaney and Logano together in bulk — if one dominates, it suppresses the other — so most builds feature one or the other, with only a handful of lineups stacking both. Josh Berry (Penske-affiliated Wood Brothers) grades out as a strong long-run/tire-conservation sleeper. The counter-question Mark keeps asking is "who can overcome their struggles?" — Byron and Elliott as possible bounce-backs, Front Row as a genuinely fast cheaper option.

The Rear-of-Field Pileup

An unusual number of quality cars are starting from the back, which drives Mark's place-differential targets. Keselowski qualified fourth but wrecked and goes to a backup; Briscoe (20th) and Hamlin (29th) both had brake failures within about five laps of practice and will likely have their full brake packages swapped, forcing them to the rear; Elliott qualified 32nd after spinning into the wall; and Ryan Preece failed inspection twice, lost his car chief and pit selection, and qualified 35th at a track he's historically strong at. Mark explains the "furthest-back qualifier drops furthest to the rear" rule and points fans to Bob Pockrass's feed for the definitive go-to-the-rear list on race day.

## Mark's Core Plays vs. Fades

## CORE PLAYS

| Driver | DK Price | Start | Role | Notes |
|---|---|---|---|---|
| Ryan Blaney | — | 1 (pole) | Dominator #1 | Fastest car, most practice laps (93), prior Iowa winner; projected 2nd, 60 laps led, 26 fast laps -> 67.7 pts. Lock all day, 30-60% of lineups. |
| Joey Logano | $9,500 | 3 | Dominator #2 / Core | "Sunday drive" qualifying lap, North Wilkesboro dominator; projected 3rd, ~25 laps led -> 54.1. Alt-dominator to Blaney, 25-55%. |
| Christopher Bell | $10,700 | 22 | Core | "Bridesmaid Bell," very consistent practice speeds; projected 5th -> 58.3. 25-55%. |
| Bubba Wallace | ~$8,000 | 26 | Core value | Track suits him, three top-10s in the comp set; projected 10th w/ 5 fast laps -> 52.3. 20-50%. |
| Chase Briscoe | — | 20 (to rear) | Core (rear PD) | Runner-up here last year, strong through traffic; projected 8th -> 49.8. 20-50%. |
| Ty Gibbs | — | 6 | Core / momentum | 2nd-fastest single-lap practice, breakout-year form; projected 4th -> 44.8. 20-40%. |
| William Byron | — | 19 | Like (not love) | Defending Iowa winner but new Chevy body has struggled; projected 10th -> 45.3. 20%+. |
| Ryan Preece | — | 35 | Rear PD sleeper | Very good at this track style, huge place-differential room; projected 18th -> 45.3. 25-50%. |
| Josh Berry | $6,900 | 13 | Sleeper | Elite long-run/tire saver; projected 9th -> 40.4, upside to 4th-5th. ~15%. |
| Todd Gilliland | $5,800 | 17 | Value | Fast Front Row car (top-4 practice speeds); projected 11th -> 37.5. Genuinely likes the call. |
| Austin Cedric | — | 12 | Dark horse | Mark's 30-1 pick to WIN; Penske speed, will be low-owned; projected ~9th -> 40.9. |

FADES
| Driver | DK Price | Start | Verdict | Reason |
|---|---|---|---|---|
| Denny Hamlin | $11,100 | 29 (to rear) | Underweight fade | Brake failure -> rear; has NEVER finished better than 24th at Iowa. Field ~35-40% owned, Mark ~20-25%. Needs 5th to be optimal; projected 14th -> 46.8. |
| Kyle Larson | — | 2 | Fade (Mark's own driver) | Chevy struggling, wreck-prone slump (3rd/4th in points down to 8th); projected 9th -> 34.1. Minimal ownership. |
| Chase Elliott | $9,000 | 32 | Fade-lean | Hendrick/Chevy can't handle new body; spun in qualifying; projected 15th -> 46.9. "When Chevy shows they're bad, they're bad." |
| Brad Keselowski | — | 4 (to backup/rear) | Fade | Wrecked in qualifying, going to a backup from the rear; projected 12th -> 24.9. Too much climb. |
| Tyler Reddick | — | 5 | Fade | Still weak at short tracks; projected 14th -> 21.9, a NEGATIVE place differential from 5th. |
| Connor Zilisch | — | 8 | Exclude | Massively out-qualified the car; ongoing "curse"; projected 24th -> 3.0. Excluded from builds. |
| Ricky Stenhouse Jr. | — | 16 | Exclude | Inconsistent, finish-where-you-start at best; projected 25th -> 9.5. Excluded. |
| Michael McDowell | — | 11 | Near-full fade | Badly out-qualified his speed (27th/23rd practice); projected 19th -> 17. Excluded. |

Key Takes

- This is a Penske race first and foremost — Blaney and Logano are the dominators to build around, and that assumption caps everyone else's ceiling.
- The field is dangerously top-heavy: after the expensive core there is almost nothing in the cheap tier, making this "a real struggle" of a build. Todd Gilliland ($5,800) and Josh Berry ($6,900) are the rare value arms worth trusting.
- Play the rear-of-field chaos for place differential: Preece (35th), Briscoe (20th->rear), and Hamlin (29th->rear) all offer PD, but only Briscoe and Preece are targets — Hamlin's Iowa history is a red flag.
- Fade the chalk on Hamlin: casual players will pile onto the most expensive car starting deep, but a brake-swap car with a 24th-place Iowa ceiling is a spot to be underweight.
- Hendrick and 23XI are quietly bad this weekend — believe the practice/qualifying signal, especially with the new Chevy body still unsolved even after a week off.

## Notable Quotes

Mark (on Denny Hamlin chalk): "The novice that's playing DraftKings is going to be like, most expensive guy starting in 29th? Heck yeah, I'm loading up on him. Hey, you do that. I'm going to fade him."

Mark (on Ryan Blaney): "I think Ryan Blaney could easily start the race, take the lead, and check out for the first stage... I'm locking him in all day long."

Mark (on Joey Logano's qualifying lap): "It looked like he was just on a Sunday drive. Hands 10 and 2, go in the corner, out of the corner... looks like he probably could have done it one-handed."

Mark (on his own driver, Kyle Larson): "He's my driver and he's done nothing other than wreck, wreck, wreck. If this downward trajectory continues, we could see our champion from last year not even make it into the chase."

Mark (on the build difficulty): "This lineup build is actually going to be really, really tough... It doesn't look pretty."

Mark (on the Chevys): "When Chevy shows they're bad, they're bad. I've learned that this year."

Mark (on Austin Cedric as a dark horse): "That's why I said it's a dark-horse pick... put $2 on him, if he wins you win 60 bucks. Loses, you're out two bucks. I'll take that chance."
