Chargers 2026 Mock Draft: Harbaugh Bulks Up Defense With PFF Projections

LOS ANGELES — The trenches just got a lot meaner. Jim Harbaugh knows you win football games by breaking the will of the man across from you, and the latest PFF 2026 NFL Mock Draft gives the Los Angeles Chargers the exact ammunition they need. Following a calculated free agency period that landed center Tyler Biadasz and guard Cole Strange, the Chargers are shifting their crosshairs to the defense. The target? A massive 326-pound wrecking ball from Ohio State named Kayden McDonald.

Harbaugh Gets His Run-Stuffer

Stopping the run remains the absolute priority for this coaching staff. Even with the addition of Dalvin Tomlinson, the middle of the defensive line needs an anchor. PFF projects Los Angeles to select McDonald with the 22nd overall pick. The former Buckeye routinely blew up double teams in the Big Ten, making life miserable for opposing running backs.

McDonald flashes terrifying power. Standing 6-foot-2 and weighing 326 pounds, he brings instant gravity to the defensive front. If he develops his pass-rush arsenal, the Chargers could have the next Haloti Ngata on their hands. You can feel the stadium shake when a guy this big hits the turf. Sitting in the scouting booth at the Combine last month, scouts audibly gasped at his explosive get-off.

Passing the Torch on the Edge

Khalil Mack returns for another run at age 35, but his sack totals are sliding. Father Time is undefeated, and the front office knows it. PFF has the Chargers snagging UCF edge rusher Malachi Lawrence in the second round (Pick 55). Lawrence exploded at the NFL Combine, measuring 6-foot-4 and 253 pounds while proving his athleticism on tape.

He terrorized quarterbacks in college, racking up 19.5 sacks and 27.5 tackles for loss. Lawrence uses a lightning-fast first step to bend the edge. Pairing him with Tuli Tuipulotu, who just finished a breakout 13.0-sack season, gives Los Angeles a terrifying young duo for the future.

“I welcome those double teams so I can free up our linebackers. I love making everybody around me better.”
— Kayden McDonald, Ohio State Defensive Tackle

Late-Round Flyers and Hidden Gems

The draft simulation didn’t ignore Justin Herbert. The front office loaded up on offensive firepower and special teams utility on Day 3:

• Pick 86 (Round 3): Michigan DT Rayshaun Benny. Harbaugh taps into his old Wolverines roster for a versatile 298-pound rotational piece.
• Pick 123 (Round 4): TCU WR Eric McAlister. The 6-foot-4 deep threat reunites with Quentin Johnston, providing a massive contested-catch target for Herbert’s rocket arm.
• Pick 204 (Round 6): Iowa WR Kaden Wetjen. The explosive 5-foot-9 specialist set a school record with six return touchdowns (four punt, two kick).

Playoff Implications / What’s Next

If this mock draft becomes reality, the Chargers drastically improve their physical identity. Harbaugh’s system demands dominance at the point of attack. By securing McDonald and Lawrence early, Los Angeles builds a defense capable of surviving the brutal AFC West gauntlet. They face a critical offseason window where maximizing Herbert’s prime aligns perfectly with fortifying the defensive front. The front office is laying the foundation for a deep January run, ensuring they don’t just compete with Kansas City, but actually bully them off the line of scrimmage.
