Per Fowler, Seahawks tight ends are “going to be moving all around” the formation this season. Whether Darnold targets TEs AJ Barner and Elijah Arroyo more often remains to be seen, but we can take this as a net positive for the offense overall. Shifts and motion give the defense an extra item to monitor. Motion added 0.25 yards per play to the NFL average last year. The 49ers averaged the fourth-highest shifts and motion rate (74.3 percent) in the 2025 regular season, while Fleury served as their run game coordinator and tight ends coach. The Seahawks’ 67.4 percent rate ranked 12th. Fleury will call plays offensively for the first time in his career, and former OC Klint Kubiak will not be easy to replace. This is an encouraging report for the Seahawks’ fantasy-scoring prospects, though.
