EAGAN, Minn. — Most NFL teams wind down during the summer. The Minnesota Vikings won’t have that luxury.Hiring general manager Nolan Teasley in June comes with cascading effects elsewhere. The staff situation remains murky. The Vikings also have a bevy of roster considerations beyond the quarterback position that require analysis and discussion.What’s on the to-do list over the coming weeks and months? Mandatory minicamp begins Tuesday, but here are the most essential matters Teasley and the Vikings will be working through.Front-office outlookThe Vikings’ timing in hiring a new general manager was interesting for many reasons. One was that it limited potential staff movement.Teams tend to finalize their scouting personnel before the summer. They enter training camp, the preseason and the fall college scouting calendar with intricate plans and processes. Because Teasley only arrived last week, the Vikings are in a rare spot.First and foremost, Teasley will need to quickly determine whether he will make adjustments to the staff. Then, if he does, plucking contractually available replacements becomes the challenge.One of the Seattle Seahawks’ underrated strengths is their continuity in the front office, a group of evaluators who have developed a shared language and worked together for more than a decade. Constructing that setup took time. He identified and hired the correct people. He empowered them. He held his staffers to a high standard, but their respect for him helped him maintain buy-in and a high work ethic.Teasley is after the same characteristics in Minnesota. Adding familiarity from Seattle might help. Surrounding himself with a former GM who could help him navigate dicey situations wouldn’t hurt, either. Few names or possibilities are worth ruling out, but whichever route Teasley and the Vikings take, it must happen quickly given the late date on the calendar.Brian O’Neill’s contractTake a poll of the Vikings players on who is the team’s foremost leader, and O’Neill’s name would surface as much as any other. The 30-year-old right tackle has been steady for eight seasons. Coach Kevin O’Connell consistently calls him one of the players he respects the most.Add in his durability and performance, and you have a player at a premium position who deserves the requisite pay. Notably, his contract is set to expire after the 2026 season.The Vikings and O’Neill’s representatives broached the subject of an extension at the NFL Scouting Combine in February. His current deal is still in place, but agreeing on the appropriate value of an extension is complicated.Last fall, the Carolina Panthers signed right tackle Taylor Moton to a two-year extension, paying him $22 million in average annual value through 2027. The Cleveland Browns recently extended right tackle Tytus Howard for $22.5 million in average annual value. O’Neill could understandably view himself as deserving of a smidge more, especially considering the year-over-year salary-cap increase.Budgeting for this could become an interesting proposition for the Vikings. The team will have to decide on Jordan Addison’s future, and Andrew Van Ginkel’s contract is scheduled to be voided after 2026. Most importantly, uncertainty around the team’s quarterback situation clouds spending elsewhere.Harrison Smith and the safety roomUnlike in previous years, Smith has delayed a potential retirement decision beyond free agency. It shouldn’t be a big deal. His understanding of defensive coordinator Brian Flores’ system minimizes the importance of spring reps. Also, the longer he waits, the clearer he’ll be on how badly he wants to continue playing.The beginning of training camp doesn’t necessarily have to be a deadline. Neither does the end of camp.Smith proved in 2025 that he didn’t have to start the season on the field to make an impact. A personal health issue sidelined him for the first couple of weeks. It also affected much of his offseason training. These setbacks slowed his ascent, a trend that coincided with the defensive dominance that helped the Vikings finish the season with five straight victories.His uncertain status puts a spotlight on the safety room. The Vikings prefer Josh Metellus near the box, while fellow veteran Theo Jackson struggled to settle into a starting role in 2025. Key responsibilities may fall to younger players. Jay Ward, a fourth-round pick in 2023, impressed late last season, while this spring, the Vikings identified Miami safety Jakobe Thomas as a potential starter.Kahlef Hailassie, a 25-year-old former undrafted player whom the Vikings didn’t want to lose, could also be a sneaky contributor.Edge-rusher depthSome elite defenses create pressure with high-end personnel. Others affect the quarterback with complicated pass-rush schemes. Flores’ defense draws from both elements, underscoring the magnitude of the move the team made this spring.Trading Jonathan Greenard to the Philadelphia Eagles places major responsibility on third-year edge rusher Dallas Turner. It also emphasizes the depth behind Turner and Van Ginkel. The scheme can only go so far. When one-on-one pass-rush opportunities present themselves, the Vikings need edge rushers who can win.Minnesota’s staff thinks highly of former undrafted edge rushers Chaz Chambliss, Bo Richter and Tyler Batty, though none of them have produced at the NFL level. The Vikings have around $13 million in cap space, according to Over The Cap, and some enticing free-agent edge rushers remain.The Vikings could wait until training camp to make a move. But from a competitiveness standpoint, supplementing this position group seems paramount.Caleb Banks’ healthTyler Williams, the Vikings’ VP of player health and performance, constructed a return-to-practice plan upon Banks’ arrival. The Vikings wanted to take a longer-term view with Banks’ recovery from a fractured fourth metatarsal in his left foot. That meant a delayed return to full activities.The team pegged training camp as the most appropriate timeline.Banks attended voluntary team activities, observing workouts and practice up close. Defensive line coach Ryan Nielsen has spent meaningful time with Banks, accelerating the youngster’s understanding of Flores’ system.Understanding Banks’ status will provide the Vikings with a roadmap for designing their defense. If he’s healthy and barreling his way toward the quarterback, the Vikings will be able to toggle with different alignments and packages. Any potential setback would put more pressure on the scheme’s ability to move opposing quarterbacks off their spot in the pocket.Blake Cashman’s futureOff-ball linebackers dictate much of what Flores wants to do defensively. He likes using them as blitzers. Their explosiveness and range also allow him to call aggressive coverages with large spaces in zones. Cashman’s combination of speed and smarts makes him a perfect fit.When healthy, his role in the Vikings’ defensive success is undeniable. But he has missed seven games in the last two seasons. These variables muddle the value for a 30-year-old linebacker whose contract expires after the season.The Vikings owe Cashman $7.5 million in cash for this season, a figure comparable to what is owed to Derrick Barnes of the Detroit Lions and Alex Singleton of the Denver Broncos. Fellow Viking Eric Wilson, who is almost two years older, signed a three-year contract this offseason worth $22.5 million. Drafting second-rounder Jake Golday gives Minnesota a possible off-ramp.However, replacing Cashman feels like a risky proposition. The Green Bay Packers recently inked Zaire Franklin to a two-year deal worth about $9 million in average annual value, perhaps a more realistic starting point to keep Minnesota-native Cashman at the center of Flores’ defense.
