The Las Vegas Raiders have been an above-average defensive unit in the last few seasons, despite not having too many household names.That was largely thanks to former Defensive Coordinator Patrick Graham, who left for the Pittsburgh Steelers this offseason. His departure paved the way for longtime Defensive Line Coach Rob Leonard to take his place.Las Vegas Raiders DL Coach Rob Leonard from Mandatory Mini-Cam | Noah Scott Fahey, Sports IllustratedWe don't know what Leonard will do, calling the entire defense, but we know he has done an excellent job developing young defensive linemen since arriving in Las Vegas in 2023. Will his teachings work for the other levels of that unit?The Raiders hope to turn things in the right direction this season, and that begins with stopping some of the best offenses they will face. Which are the best units they'll see?Let's break down the best three offensive units on the Raiders' schedule.Buffalo Bills - Week 6Sep 17, 2023; Orchard Park, New York, USA; Buffalo Bills offensive tackle Spencer Brown (79) prepares to block Las Vegas Raiders defensive end Maxx Crosby (98) to protect quarterback Josh Allen (17) in the fourth quarter at Highmark Stadium.

It doesn't hurt that he still has last year's leading rusher, James Cook, in the fold.Buffalo Bills running back James Cook III looks to the sidelines as the teams change positions at the end of the third quarter at Empower Field at Mile High in Denver, Colorado on Jan. 17, 2026. | Tina MacIntyre-Yee/Democrat and Chronicle / USA TODAY NETWORK via Imagn ImagesThe Bills also added wide receiver D.J. Moore in a trade, giving Allen a reliable weapon on the outside. The Raiders will have their hands full dealing with the MVP QB, an elite running back, and pass-catchers like Moore, Khalil Shakir, and Dalton Kincaid.Los Angeles Rams - Week 7Oct 20, 2024; Inglewood, California, USA; Los Angeles Rams quarterback Matthew Stafford (9) calls a play during the second half against the Las Vegas Raiders at SoFi Stadium.

However, they make their money on offense.Featuring one of the best play-calling head coaches the NFL has ever seen in Sean McVay and last year's MVP in Matthew Stafford, not many teams have been able to figure out Los Angeles. Add in Puka Nacua, former Raider Davante Adams, and Kyren Williams, and you see why this group dominates.Jan 10, 2026; Charlotte, NC, USA; Los Angeles Rams wide receiver Davante Adams (17) makes a catch against Carolina Panthers cornerback Mike Jackson (2) in the first half during the NFC Wild Card Round game at Bank of America Stadium.

However, Los Angeles may be the best offense they face all season.Los Angeles Chargers - Weeks 2 and 14Oct 1, 2023; Inglewood, California, USA; Los Angeles Chargers quarterback Justin Herbert (10) is sacked by Las Vegas Raiders defensive end Maxx Crosby (98) in the fourth quarter at SoFi Stadium.

Now, he has an efficient play caller who will help unlock some of the weapons within Los Angeles' offense.May 20, 2026; Henderson, NV, USA; Las Vegas Raiders head coach Klint Kubiak speaks during a news conference during organized team activities at Intermountain Health Performance Center.
