It’s the question that haunted every waiver wire addict and dynasty manager throughout the latter half of 2025: what are we supposed to do with Mike Williams? If you drafted him hoping for that classic "Big Mike" resurgence with Justin Herbert, you’ve likely spent the last few months oscillating between nostalgia and pure frustration.
Football is a brutal business. Honestly, watching a 6'4" vertical threat lose that explosive first step is one of the hardest things to track in real-time. For years, Mike Williams was the king of the "50-50 ball," a guy who turned contested situations into highlight reels. But by the time we hit the 2026 offseason, the landscape changed completely.
Mike Williams Fantasy Football: The Retirement Shock
Let's address the elephant in the room first. On July 17, 2025, Adam Schefter dropped the news that essentially nuked 10% of Underdog Fantasy drafts: Mike Williams retired. After signing a one-year, $6 million "homecoming" deal with the Los Angeles Chargers in March, the veteran wideout decided he’d had enough. He had spent the spring on the Active/PUP list with an undisclosed injury, and apparently, the body just wasn't responding the way it used to. He stepped away from the game after eight seasons, 32 touchdowns, and two 1,000-yard campaigns.
Wait. So why are people still searching for his fantasy value in 2026?

Because in the world of fantasy sports, "retired" sometimes feels like a temporary status, and the ghost of Mike Williams’ production still looms over the Chargers’ depth chart. People are looking for the next Mike Williams, or they’re checking to see if a mid-season comeback is in the cards. Spoiler alert: it’s not. He’s done. But the vacuum he left behind is exactly what's driving the 2026 fantasy market for the Bolts.
Life After Big Mike in Los Angeles
When Williams walked away, Jim Harbaugh and Joe Hortiz didn’t panic. They did something much more "Harbaugh-esque"—they brought back Keenan Allen.
It’s wild how the 2025 season played out. While everyone was scouting rookies like Tre Harris, it was the old guard that kept the lights on. But even with Allen back in the building for the 2025 campaign, the "Mike Williams role"—that vertical, X-receiver spot—was never truly filled.

- Ladd McConkey became the clear alpha, leading the team in receiving yards.
- Keenan Allen stayed productive at age 33, racking up 81 catches for 777 yards.
- Quentin Johnston... well, he’s still trying to find that consistency we've been waiting for.
Basically, the 2025 Chargers offense lacked that terrifying deep threat that Williams provided at his peak. They failed to reach the end zone in their Wild Card loss to the Patriots, a game where they desperately needed a big-bodied receiver to win a jump ball in the red zone. That’s the "Mike Williams effect." You don't miss it until you're staring at a 19-3 scoreboard in the playoffs.
The Dynasty Fallout and 2026 Projections
If you’re still holding Mike Williams in a dynasty league, it’s over. You can officially move him to your "Retired" or "Taxi" graveyard. However, his departure has created a massive opportunity for the 2026 season.
Right now, expert rankings for 2026 are heavily favoring the younger core in LA. Without Williams or a clear veteran deep threat, the target share is up for grabs. Tre Harris and KeAndre Lambert-Smith are the names you'll hear in every "sleeper" podcast this summer. Harris, in particular, has that size-speed combo that reminds scouts of a younger Williams.

Honestly, the Chargers' inability to find a 1,000-yard receiver in 2025 tells you everything you need to know. The volume is there. Justin Herbert is still a top-tier talent. But the efficiency is missing. If you’re drafting for 2026, you aren't looking for Mike Williams; you’re looking for the guy the Chargers sign or draft to replace his specific skill set.
Why the "Big Mike" Archetype is Hard to Replace
It’s easy to say "just draft a tall guy." It's harder to find someone with the timing Williams had.
During his 2021 breakout—his career-best year—he hauled in 76 catches for 1,146 yards and nine scores. He wasn't just tall; he was a master of body positioning. Most receivers today are "separators"—they win with routes. Williams won with leverage.
In 2024, split between the Jets and the Steelers, we saw the decline. He had a modest 21 catches for 298 yards across 18 games. That's a 16.5-yard average, which looks okay on paper, but he was barely targeted. In Pittsburgh, he was an afterthought, catching just nine balls in nine games. The "boom-or-bust" nature of his fantasy profile finally became all "bust."
Actionable Insights for Your 2026 Drafts
- Stop chasing the comeback. Mike Williams is retired. Don't let a "what if" roster spot waste a bench stash in your dynasty league.
- Pivot to Ladd McConkey. He is the undisputed WR1 in this offense. In 2025, he proved he can handle the volume even without a vertical threat clearing out the safety.
- Monitor the Chargers' Offseason. GM Joe Hortiz has already hinted at wanting Keenan Allen back, but they need a "Z" or "X" receiver who can stretch the field. If they draft a receiver in the first two rounds of the 2026 NFL Draft, that is your Mike Williams replacement.
- Value "Contested Catch" Specialists. In standard scoring leagues, Williams was a gold mine because of his TD upside. Look for players like George Pickens or Drake London who share that high-point ability.
The era of Mike Williams in fantasy football was a rollercoaster. He won you weeks single-handedly and then disappeared for a month. Now that he's officially hung up the cleats, the smartest thing you can do is study the targets he left behind. The Chargers' offense is evolving, and while it might be more "blue-collar" under Harbaugh, there is a massive WR2 hole that needs to be filled for 2026.
