The 2026 college football season is almost here, and a handful of players are shaping up to be absolutely vital for their teams. These guys aren’t just good—they’re the kind of athletes whose absence could throw a whole season off track.
Let’s look at seven standouts who, if sidelined, would leave their programs scrambling. We’re talking quarterbacks, defensive anchors, and more. In a time when NIL deals and roster shuffling make depth a constant headache, these players are more crucial than ever.
CJ Carr: The Quarterback Notre Dame Can’t Afford to Lose
So, heading into his second year as Notre Dame’s starting quarterback, CJ Carr has a lot on his shoulders. After a breakout redshirt freshman year—2,741 yards, 24 touchdowns—he’s the centerpiece of a team with sky-high expectations.
Notre Dame’s quarterback depth is, well, a bit shaky. There are promising freshmen like Noah Grubbs and Teddy Jarrard, but if Carr went down, redshirt freshman Blake Hebert (who hasn’t really played) would be up next. That’s a risky spot for a team with playoff hopes.
Why CJ Carr is Irreplaceable
Honestly, Carr’s experience and production set him apart. He runs the offense with a calm precision that’s just not there in the backups.
If Notre Dame wants to stay in the title hunt, they need Carr healthy and on the field. Simple as that.
Colin Simmons: Texas’ Defensive Cornerstone
Colin Simmons might be the best defensive player in college football heading into 2026. Texas has plenty of talent at edge, like Lance Jackson and Colton Vasek, but Simmons is on another level.
With Will Muschamp calling the defense now, Simmons is expected to be a sack machine and the focal point of a unit that could carry Texas deep into the postseason.
The Impact of Colin Simmons
Simmons just disrupts offenses in a way few can. He’s got a knack for big plays and getting after the quarterback.
If Texas is going to make a serious run, Simmons will be leading the charge. No question about it.
Kewan Lacy: The Engine of Ole Miss’ Offense
Transferring in from Missouri, Kewan Lacy has quickly become the heart of the Ole Miss attack. Last season? 1,567 yards, 24 touchdowns—he’s the guy defenses have to stop.
The Rebels have a new look on offense, but they’ll be leaning heavily on Lacy to keep things rolling. Makhi Frazier and Joshua Dye are interesting, but let’s be real—Lacy is the one that makes this offense go.
Why Kewan Lacy is Indispensable
Lacy just finds ways to break games open. His experience and skill set are a step above anyone else on the roster.
Without him, Ole Miss would be searching for answers all season.
Jayden Maiava: USC’s Quarterback Hope
Jayden Maiava is the latest in a line of USC quarterbacks under Lincoln Riley, and expectations are high. As a redshirt junior, he’s supposed to guide the Trojans through the Big Ten gauntlet and maybe into the Playoff.
USC’s receiving corps has changed a lot, so Maiava’s job is even tougher. Jonas Williams, a true freshman, might be the future, but he’s not ready yet. Sam Huard brings some experience but isn’t expected to start.
Maiava’s Crucial Role
Maiava’s leadership and ability to adjust will be huge for USC. He’s got to make it work with a new group of receivers.
If he’s out for any stretch, USC’s offense could hit a serious wall.
Texas Tech’s Vital Piece: Hammond
After Brendan Sorsby’s exit, Hammond suddenly finds himself in a huge spot for Texas Tech. He’s had flashes in limited time, but 2026 is when he really needs to deliver.
Coming off a Big 12 title and a Playoff appearance, Texas Tech just needs Hammond to keep the ship steady. Even if he’s just a reliable game manager, that might be enough.
Hammond’s Importance
Hammond’s steadiness under center is what Texas Tech is counting on. There’s talent waiting in the wings, but this season, it’s Hammond or bust.
BYU’s All-Purpose Star: Martin
Martin is BYU’s do-it-all back, racking up 1,305 yards and 12 touchdowns last year. There’s not much proven depth behind him, which makes his role even bigger.
Quarterback Bear Bachmeier and receiver Parker Kingston were next in rushing yards, which… isn’t ideal. If BYU’s going to contend, they need Martin to stay healthy and productive.
Martin’s Indispensable Role
Martin’s versatility gives BYU a real edge. He can hurt defenses on the ground and through the air.
Losing him would leave the Cougars scrambling for answers.
Miami’s Offensive Line Anchor: Cantwell
Cantwell is a five-star true freshman, and he’s already penciled in as Miami’s starting left tackle. At 6-7 and 330 pounds, he’s got the size, but he’s also got a tough job protecting the blindside.
With Francis Mauigoa and Markell Bell gone, Miami’s depth at tackle is, honestly, pretty thin. If Cantwell misses time, the Hurricanes could be in serious trouble up front.
Cantwell’s Crucial Role
Cantwell’s size gives him a real edge on Miami’s offensive line. He’s got a skill set that just fits right in.
He’s not just there to block—protecting the quarterback and holding down the line are both on his shoulders. If the Hurricanes want a shot at real success in 2026, they’ll need him healthy and locked in.
