NFL DFS Lineup Picks for FanDuel, DraftKings - Vikings vs. Steelers Sunday Showdown (Dublin Game)

Koby's top NFL DFS lineup picks for DraftKings, FanDuel -- Vikings vs. Steelers showdown slate for Week 4 Sunday morning Dublin game. His NFL daily fantasy sleeper picks.

Welcome back, RotoBallers! Thursday Night Football was starting to look like a blowout, but the Cardinals came back and tied it up late. A costly kickoff mistake led to the Seahawks getting great field position and winning the game with seconds on the clock. We get a 9:30 am start for this one, and for those of us on the West Coast, we get to wake up early at 6:30 am to start our Sundays off early!

For the next few weeks, we will get some international games. For this one, we travel to Dublin, Ireland, for the first time in league history. They get an interesting matchup between the 2-1 Minnesota Vikings and the 2-1 Pittsburgh Steelers. Carson Wentz and the defense led the team to a big win against the Bengals and were able to get the Vikings back on track. The Steelers look to capitalize on their win against the Patriots last week and hope to advance to 3-1 on the season.

I will provide you with daily fantasy football picks on DraftKings and FanDuel for the Sunday Morning Football game in Dublin, Ireland for Week 4 -- Vikings vs. Steelers on September 28, 2025. These NFL DFS lineup picks can vary from higher-priced players and elite options to lower-priced players and value picks.

MVP/Captain - NFL DFS Lineup Picks

Carson Wentz - QB, $13.5K (DK), $16.8K (FD)

Carson Wentz truly revived this Vikings team. After an abysmal Week 2 from J.J. McCarthy, Wentz stepped in due to injury. He had a solid outing against the Bengals, throwing for two touchdowns and 173 yards before getting scripted out due to a blowout. The Steelers have been giving up quite a bit of fantasy points to opposing QBs this season, with the fifth most in the league.

I imagine we see the passing game more on display for this one, as the Steelers should be able to keep it much closer than the Bengals did last week. This puts Wentz in a prime position to perform well and hopefully score higher than his 15 fantasy points in Week 3.

Jordan Mason - RB, $15.6K (DK), $17.7K (FD)

I think there are likely two game scripts here: one that heavily involves Jordan Mason, and another that ends in a more passing attack. Jordan Mason exploded last week with 116 rushing yards and two touchdowns. He wasn't involved in the passing game; that could have been because of a blowout and not needing it, or that's how it could be going forward until Aaron Jones Sr. returns to the lineup.

The Steelers' defense has done well against the run game so far, as they are in the bottom half in fantasy points allowed to running backs. The Steelers' offense hasn't been lethal enough to warrant putting one of them at the MVP spot, and the Vikings' defense was on another level last week. I'm not thinking blowout, but this one could be in favor of the Vikings pretty heavily, and if that's the case, I want a little bit of Mason in the MVP spot. Who knows, he could go off for 26 fantasy points again!

Other Captains/MVPs: Justin Jefferson, DK Metcalf

Flex Plays - NFL DFS Lineup Picks

Calvin Austin III - WR, $6.2K (DK), $7.2K (FD)

Calvin Austin III has become the clear WR2 in this offense, and the Steelers haven't shown much interest in running more than two receivers with multiple options at TE as well. Last week, only Metcalf and Austin had more than 20% of snaps played. Austin is still relatively cheap and has already had two weeks of double-digit fantasy points this year.

— Jordan Schultz (@Schultz_Report) September 21, 2025

He has benefited from a couple of shots in the end zone this season, but with five or more targets in two weeks and a 70% snap share this season, I think we are getting incredible value on Austin in this one. Especially if the Vikings get up early in this one, and Aaron Rodgers has to start throwing the ball downfield more.

Jordan Addison- WR, $7K (DK), $9.2K (FD)

This one is a bit risky. Jordan Addison will look to make his debut, and I'm not quite sure how much of an immediate role he will have in the offense or if he will be limited in any way due to conditioning. Addison has too much potential, though, as he was a lethal part of this offense last season. Between his previous six games, he was targeted eight or more times in five of them. Obviously, he has someone new at the helm, but Carson Wentz is going to throw the ball and hopefully get Addison involved early.

Other Flex Options: Aaron Rodgers, DK Metcalf, Jaylen Warren

Value Plays - NFL DFS Lineup Picks

T.J. Hockenson - TE, $5.4K (DK), $7.8K (FD)

This one is a bit high-end for pricing, but Hockenson finally got involved in the offense last week with Wentz at QB, and that can't be a coincidence. He is also getting a spectacular matchup here against the Steelers, who have so far ranked the worst against TEs. They give up the most fantasy points to opposing TEs out of any team this season. Josh Oliver stole a touchdown in last week's matchup, but Hockenson is so due for some more targets in the endzone after finally getting one of them last week.

Jonnu Smith - WR, $3K (DK), $5K (FD)

It's crazy that Jonnu Smith went from a career year to what we have seen from him so far this season. It is a bit disappointing to see him with only 12 receptions on 13 targets so far this season. I think getting a little bit of both Smith and Pat Freiermuth in separate lineups could be big. I think one of these guys is due for a big performance. Smith is coming off a game where he played 83% of the snaps.

Smith has been questionable with a hip injury all week, but was able to log limited practices both Thursday and Friday. If, for some reason, Smith isn't able to go, then locking in Freiermuth is a must, as he could be in for a massive share of the TE duties if Smith is absent.

Other Value Options: Minnesota D/ST, Chris Boswell, Pat Freiermuth
