Players To Watch

Julian Sayin

QB · Ohio State Buckeyes

Ohio State's offense turned in its most explosive passing performance of the season last week, with Julian Sayin at the center of it. He threw for a season-high 367 yards and four touchdowns on 27-of-36 passing against Illinois, adding 29 rushing yards and a score on the ground. This season he has 1,206 yards, 10 touchdowns and just one interception through four games.

Iowa's defense enters off a road win at Michigan in which it forced a red-zone interception and got double-digit tackle games from three different players. That kind of takeaway-minded unit is a step up from anything Sayin has faced so far this season.

Jeremiah Smith

WR · Ohio State Buckeyes

Iowa's coaching staff already has named its central defensive question for Saturday, and it starts with containing Jeremiah Smith. He set a new career high with 12 catches for 217 yards and four touchdowns against Illinois last week, tying Ohio State's single-game touchdown-reception record, and he'd already become the program's career receiving yards leader earlier this season.

Iowa is 4-0 and ranked 14th, but needed a touchdown with two seconds left to beat Michigan 20-19 last week. Smith gives Ohio State a scoring threat capable of deciding a game that tight.

Hank Brown

QB · Iowa Hawkeyes

Hank Brown delivered the biggest throw of his season when it mattered most last week. He was 21 of 35 for a season-high 227 yards and two touchdowns in Iowa's 20-19 win at Michigan, capped by a 16-yard touchdown pass to Reece Vander Zee with two seconds left. He has 700 yards, five touchdowns and zero interceptions this season.

Ohio State is averaging 45 points a game this season, a different level of firepower than anything Brown has had to match so far in 2026.

Cam Buffington

LB · Iowa Hawkeyes

Iowa's front seven will have to slow one of the country's most explosive offenses Saturday, and Cam Buffington has been the one making plays up front to do it. He turned in a season-high 11 tackles in last week's 20-19 win over Michigan, anchoring an Iowa front that also picked off a pass in the red zone that day.

Jeremiah Smith alone accounted for four touchdowns and 217 receiving yards in last week's win over Illinois, the kind of big-play receiving threat Iowa's front seven has not had to defend as often as it will now.
