​Will Seattle Seahawks tight end AJ Barner emerge as a surprise performer in the realm of fantasy football this season?Barner is an intriguing option to consider utilizing as a flex player moving forward, as his most recent play in Week 3 has reflected that of what he showed in 2025 as a productive pass-catcher in the Seahawks’ offense. Barner started all 17 games for the Seahawks in 2025, catching 52 passes for 519 yards and six touchdowns. The production marked a significant increase from his rookie season and gave fantasy managers a glimpse of his potential.However, Barner has gotten off to a slow start to the current season. He has recorded eight receptions for 90 yards and has yet to score a REC touchdown on the year. Nevertheless, he most recently went for 69 REC yards on five receptions in Week 3, looking more like the type of player he was forecasted to be leading up to the season. Sam Darnold’s prolific performance in his return from injury in that game offers more hope that more of that type of play will now be in store for Barner.Barner’s starting role and red-zone involvement provide reasons for optimism for fantasy football team managers looking for a scoring threat who is capable of having big games in the receiving yards department. If Seattle expands his role in the passing game, Barner may indeed outperform his ADP and develop into a valuable starting option in 2026.This article originally appeared on Seahawks Wire: Seahawks TE AJ Barner carries interesting fantasy football flex value
