Brian O’Neill’s Return Unlocks Justin Jefferson’s Ceiling Just in Time for a Playoff Push: Offensive Lines and Their Fantasy Impact, Week 10

November 8, 2025

After leading last week’s column about how critical Joe Alt’s return to the lineup would be for Justin Herbert and company, the Chargers’ injury luck went and struck again.

Now they’re kicking the tires on Saints first-rounder Trevor Penning in the hopes he can hit the OT growth curve in Year 4. A change in scenery, coach, and quarterback seemed worth the swing for Coach Jim Harbaugh and GM Joe Hortiz when only dealing a future sixth-rounder at the trade deadline. Penning has mixed a few highs with general struggles at both tackle and guard during his time in New Orleans.

Other teams saw severe disruptions in offensive line continuity before they even trotted out their starting lineup last week. Let’s dive in.

Who’s losing and returning fixtures on the starting OL?

Three offensive lines recently lost continuity in terms of incumbent starters, and four units gained it by getting those incumbents back on the field.

Does Joe Alt’s Return Make Justin Herbert a Top Fantasy Option? Offensive Lines and Their Fantasy Impact, Week 9

Thomas Emerick October 30, 2025

The tip of the Chargers’ spear had been dulled without both Joe Alt and Rashawn Slater. Passing efficiency had slowed in late September and October for a unit that produced bona fide fantasy starters through the league’s first month in Justin Herbert, Keenan Allen, and Quentin Johnston. Slater is done for 2025, but Alt’s return last Thursday generates a sustainable second wind for a Bolts offense now helping…...

Jahmyr Gibbs’ Turnaround with Taylor Decker’s Return and 6 More Fantasy-Relevant OL Changes: Offensive Lines and the Fantasy Impacts, Week 8

Thomas Emerick October 25, 2025

A much-needed week for the Jahmyr Gibbs bags started with Taylor Decker returning at left tackle for the Detroit Lions. Decker had missed the previous two weeks, and the ROI on that top-5 pick nosedived. Gibbs went off on Monday night, mostly because he’s very good, though it also helped that the tackle play improved dramatically. The previous two games saw different LT backups in Giovanni Manu…...

Zach Tom’s Return Unleashes Green Bay’s Explosive Potential: Offensive Lines and Their Fantasy Impact, Week 7

Thomas Emerick October 16, 2025

Packers RT Zach Tom played sparingly before the bye due to an oblique injury, which became a real problem when Jordan Love and company faced reasonable opposition in Cleveland and Detroit. Green Bay’s fourth-year starter was among the top right tackles last season, and last week his return ushered in one solitary pressure and zero QB hits from the RT assignment. While injuries hammer the receiver position for Green…...
