The Minnesota Vikings struck gold in the 2018 NFL Draft when they selected Brian O'Neill out of Pittsburgh in the second round. Since then, he's been nothing short of a cornerstone—a reliable, high-performing tackle who anchors the right side of the line with the kind of consistency every offensive coordinator dreams of.

In recent seasons, the Vikings have made a clear commitment to fortifying their offensive front. Last year, they launched an all-out renovation of the interior line, bringing in first-round pick Donovan Jackson at left guard, veteran center Ryan Kelly via free agency, and guard Will Fries on a major deal. On paper, it looked like a formidable unit. In reality, injuries, inconsistent play, and questionable offensive schemes kept the group from reaching its potential.

Now, as we look ahead to 2026, the lineup remains largely intact—with one notable exception. Kelly has retired from football, leaving Blake Brandel as the frontrunner to take over at center. Continuity is the theme, but the question lingers: could this be O'Neill's final season in Minnesota?

Let's be clear—O'Neill can still play at a high level. But the Vikings have started stockpiling tackle depth, and that's worth paying attention to.

Back in March, the team signed Ryan Van Demark away from Buffalo, signaling the end of Justin Skule's tenure as the primary backup tackle. On its own, that move was about solidifying the OT3 spot—nothing more, nothing less. But then came the 2026 NFL Draft, where Minnesota selected offensive tackle Caleb Tiernan with the 97th overall pick. That decision carries weight—both now and for the future.

Tiernan was widely considered a steal at that spot. Draft analysts had him graded much higher, and for good reason. Lance Zierlein's scouting report highlights a "highly experienced college tackle" who may need to kick inside due to length concerns, but brings impressive quickness, excellent angles in space, and a dense, powerful frame. He's the kind of versatile, technically sound lineman who could develop into a long-term starter—and that might spell the beginning of the end for O'Neill in purple.

For now, the Vikings are building depth and planning for the future. But if Tiernan proves ready sooner than expected, the team could face a tough decision—one that might send one of their most dependable players elsewhere. Stay tuned, because the offensive line puzzle in Minnesota is far from finished.
