​LAWRENCE — There’s going to be a lot of attention on how Isaiah Marshall performs as Kansas football’s starting quarterback this fall.Marshall, a redshirt sophomore, is going to be leading the way for the Jayhawks offense. He’s taking over for Jalon Daniels, who’s now pursuing a professional career. KU is aiming for a bounce-back season and Marshall’s play will go a long way toward determining that.RELATED: What will Kansas football’s stadium capacity be during 2026 season?Here are some thoughts about other aspects of the offense, though, from associate head coach Andy Kotelnicki as Kotelnicki spoke at the team’s media day in August before the revelation Marshall would start:How Andy Kotelnicki views Kansas’ offensive lineKotelnicki wants the offense’s overall identity to showcase physicality and effort, and give the best players ample opportunities to make plays. He thinks they can be diverse offensively, and explosive, while still being rooted in toughness. Much of how Kansas can meet that goal will come down to how the offensive line performs.KU continues to cross-train certain offensive linemen so they’re able to have the best five guys on the field at any given time. That includes a guy like redshirt sophomore DeAndre Harper playing both guard and tackle, and redshirt junior Amir Herring playing both center and guard. Redshirt junior Calvin Clements’ leadership has also shown up, as both his improvement in pass protection and ability to embrace the necessary physicality needed.How Kansas’ wide receivers are performingKansas’ wide receivers room has a lot of potential in 2026, including redshirt senior Nik McMillan as someone who could lead the way. Kotelnicki has been pleased with what McMillan’s done, and overall the room has done well to step up to the demands presented to it during fall camp to make plays. Although redshirt senior Cam Pickett missed some time, it wasn’t something that sounded like a significant concern.Redshirt senior Nahzae Cox and redshirt junior Keaton Kubecka are two more standouts. Sophomore Tate Nagy has improved a lot, too. Nagy’s an athlete who’s always been very coachable, while Kubecka is someone who continues to show what they’re looking for in practice — not just making plays here and there, but consistently making plays.What Andy Kotelnicki is seeing at running backAt running back, redshirt sophomore Jalen Dupree has been able to take advantage of practicing more in fall camp. Kotelnicki likes Dupree’s vision, and his ability to run with toughness and physicality. Dupree is capable of giving the room some depth if he remains healthy.Junior Yasin Willis brings size to the room, as well as physicality. He’s someone Kotelnicki thinks will be able to break a ton of arm tackles, and that and more has Kotelnicki excited to see him in games. Willis should form a dynamic duo with redshirt junior Dylan Edwards.What Andy Kotelnicki is still looking for from the offenseKotelnic
