September gave us an early look at the prospects shaping the 2027 NFL Draft class, but this weekend should tell us more about how they handle the tougher competition.

Many top quarterbacks faced their toughest defensive assignments yet, as eight of the nation’s top 12 teams came through. Here are the matchups to watch, starting with the most draft-loaded game on the schedule.

Proud of Iowa vs. Ohio State has the most talent

With 11 players on the big board for the 2027 NFL Draft, Iowa’s matchup with Ohio State features more talent than any other game this weekend. It also presented Julian Sayin with his toughest defensive challenge.

Sayin’s lack of ideal size and arm strength have prompted questions about his NFL outlook, but his production is becoming hard to ignore. Last week marked his sixth career game with a PFF grade above 90.0, and he finished September as the second-highest graded passer in college football.

The best matchup, however, may come in the trenches. Ohio State edge defender Kenyatta Jackson Jr., ranked 40th on the PFF big board, faces an Iowa offensive line that features the No. 34 Trevor Lauck and No. 37 Kade Pieper.

Jackson has been a steady run defender throughout his Ohio State career, with his season-long PFF run-defense grades ranging from 60.0 to 75.0. Meanwhile, Lauck has been an outstanding pass protector despite playing in a run-heavy offense. He has allowed just seven pressures in 400 career pass-blocking snaps and has yet to surrender a sack as a Hawkeye.

Iowa’s offensive line already passed a significant test in last week’s victory against Michigan, holding highly regarded edge defender John Henry Daley to a 61.7 PFF pass-rushing grade, his lowest as a collegiate starter.

Jackson isn’t the same caliber of prospect we’re used to seeing on Ohio State’s defensive line, but his continued production and physical attributes should still garner interest in the first round. Questions remain about his ceiling, so a strong performance against Iowa would provide a significant boost to his draft stock.

Can Alabama’s top defenders squash Super Kamario Taylor?

Alabama will face one of the most exciting players in college football this weekend when it travels to Starkville to take on Mississippi State and quarterback Kamario Taylor. Not eligible for the draft until 2028, Taylor is already generating buzz as a potential future No. 1 pick, with his electric style of play drawing comparisons to former Heisman Trophy winner Lamar Jackson.

Most of the attention coming into this game was focused on the promising quarterbacks on both sides, but Taylor has never faced a defense with this much talent. Alabama may not have the depth of the incredible defenses coached by Nick Saban, but the 2026 unit still features the 2027 draft’s third-ranked edge defender in Yhonzae Pierre, fifth-ranked cornerback in Zabien Brown and sixth-ranked safety in Bray Hubbard.

Pierre recorded two sacks in four games, albeit on just 65 pass-rushing snaps. He has yet to make the leap many expected this season, and ending pressures against Taylor will present a particular challenge. Taylor will likely be the most elusive quarterback Pierre will face all year.

Neither Brown nor Hubbard reached full stride in the secondary, although Hubbard’s start raised more questions. Despite the pass interception against Florida State, he earned a 62.3 overall PFF grade this season. That represents a big drop from his 83.1 grade last year and his elite 89.2 mark in 2024.

As a former three-star recruit, Hubbard doesn’t have the athletic upside of some other defensive backs in the Alabama secondary. Because of this, his production carries more weight in his evaluation, and he needs to show that he can continue to perform at a high level.

Darian Mensah’s first proper test as a Hurricane

With so many quarterbacks to settle between now and April, each weekend adds another useful piece of evidence. For Darian Mensah, this road trip to Clemson should provide the clearest indication yet of where he belongs.

As mentioned earlier, Julian Sayin is the second highest scorer in college football this season. Mensah is the only player above him. The Miami quarterback was outstanding, posting a 154.0 passer rating without recording a turnover-worthy play.

His victory over Wake Forest looks even stronger now following the Demon Deacons’ upset of ranked Louisville, but Miami still faces one of the easiest opening schedules among the contending programs. Mensah currently sits 45th on PFF’s big board, and a strong performance at Clemson could push him into the first-round conversation, if he isn’t already there.

Clemson didn’t bow down. The Tigers have four defenders inside PFF’s top 90, and their sluggish start appears to be behind them. Last week, they held promising 2028 quarterback prospect Jaron Keawe-Sagapolutele to a career-low 55.7 PFF passing grade. Cal’s quarterback threw two interceptions and struggled against pressure from edge defender Will Heldt, the No. 51 players on the PFF board.

Mensah can always turn to dynamic sophomore Malachi Toney if Clemson’s rush forces him to get the ball out quickly. That sets up another intriguing matchup with cornerback Ashton Hampton, who carries a first-round grade from PFF. Hampton has missed just five tackles since the start of last season, while Toney has forced 48 missed tackles over the same span.

Which top players can handle the road environment?

After an opening month dominated by non-conference home games, eight of college football’s top 12 teams hit the road this weekend. Those teams account for 43 players on PFF’s top-150 draft board.

Beyond Ohio State, Alabama and Miami, reigning national champion Indiana faces an interesting trip to Rutgers after surviving a one-score scare against Northwestern last week. The Scarlet Knights don’t have anywhere near the depth of talent on Curt Cignetti’s roster, but wide receiver KJ Duff already has 550 receiving yards, including 11 catches of at least 15 yards. Currently ranked 28th overall, he could be a first-round lock if he continues to play at this level.

Indiana’s Kamari Sharpe, PFF’s sixth-ranked cornerback in the 2027 class, will be assigned to fill in for Duff. Sharpe has good size at 6-foot-1, but Duff’s 6-foot-6, 225-pound frame creates a mismatch against any college cornerback. Rutgers will likely need to throw to keep up with the Hoosiers, giving this matchup plenty of opportunities to influence the game.

Also keep an eye on BYU running back LJ Martin during the Cougars’ trip to TCU. Only 5.5 points favor 10th-ranked BYU, and the home crowd should recognize a real opportunity for a top-10 upset.

Martin has been a standout at BYU for years, but he was passed over by Florida’s Jadan Baugh and Georgia’s Nate Frazier to start 2026. With limited running back space in the middle rounds, a strong performance on the road could help Martin bolster his position in the class.
