San Francisco 49ers Fantasy Preview

Mr. Irrelevant? More like anything but! Brock Purdy’s playing like a man possessed, trailing only Josh Allen in positional scoring but with better throwing stats. Purdy’s 126.2 passer rating and 9.7% TD rate lead the league, not to mention he’s averaging over 30 yards on the ground per game, and hasn’t eaten a single sack in 2026. Not one! And this production’s occurring in positive game scripts — the Niners spent less than 15% of plays trailing. Wow.

San Fran’s running back situation’s always relatively clear so long as Christian McCaffrey’s on two legs. Nevertheless, it’s worth mentioning we’re a full month into the season, and he’s yet to log 20 touches in a single contest. Now, it barely matters since CMC’s so efficient in the pass game, plus he’s leading all RBs in team target share (20.0%) — but that’s why he’s our RB9 and not the RB4. Maybe Seattle keeps this close enough to finally get over the hump. Lastly, rookie Kaelon Black has played well enough to secure the backup role and holds some relatively quiet but massive contingency value.

Quick show of appreciation to Kyle Shanahan for making fantasy football so easy. When he loses a player to the substation or otherwise, those vacated targets will not be going to some retread off the street — it gets tossed on the plate of San Fran’s pre-rostered stars. The Niners’ three-headed pass-catching monster of Mike Evans, George Kittle, and Deebo Samuel soaked up +58% of all targets this season, which actually spikes over 78% if you include McCaffrey. No surprises where the ball’s going, and Purdy’s still throwing for just under nine yards/attempt. Impressive stuff.  

Seattle’s D deserves some digital real estate (4.0 yards/play, 59.1% success rate, +0.16 EPA/play), but they do run an almost exclusively zone-only defensive package — which is susceptible to getting beaten in soft spots underneath. We just saw a perfect example of efficiency overcoming the Seahawks when the Commanders hung 33 points in a Week 3 victory.

• Start: QB Brock Purdy, RB Christian McCaffrey, WR Mike Evans, WR Deebo Samuel, TE George Kittle
• Sit: WR Jordan Watkins
• Sleeper: RB Kaelon Black

Seattle Seahawks Fantasy Preview

Seattle’s an interesting test case in pace plus efficiency and how it resonates through our rosters. Generally, a team scoring over 26 PPG at nearly six yards a clip would be the apple of our fantasy eyes. However, at 59.3 plays/game, 5.0 plays/drive, and an 8.3 average play clock at snap, there’s very little besides the obvious to get excited about.

Before getting into the action-green and wolf-grey elephant in the room (yes, I researched SEA’s official team colors) the same volume issues I mentioned cap their QB ceilings. Whether it’s Sam Darnold under center or his competent facsimile Drew Lock, neither averaged more than 25.5 dropbacks/game. Strike one. Then factor in a non-existent scramble element to their game, and there goes any reliable fantasy floor. Strike two, you’re out.

Seattle merely exists to force-feed Jaxon Smith-Njigba the ball, and from the looks of it, that plan appears to be working just fine. Not just the owner of the NFL’s highest team target share, JSN’s 36.5% target rate sits nearly five full ticks higher than anyone else. To put that in perspective, he’s an entire secondary player’s workload ahead of all the league’s best pass catchers. Crazy stuff.

Try and find whichever analyst pitched you inevitable year-over-year regression, and ask them how to project Smith-Njigba’s insane combination of stats going forward: UR 98, 120.3 receiving yards/game, 36.2% target/route, 4.15 yards/route, 4.6 routes/1st down, 91.4% WOPR. It's like a video game in need of a difficulty settings correction …  

Until Seattle figures out a way to clone JSN so he can also handle the backfield carries, it looks like Emanuel Wilson‘s the man for the job. Still bottom-5 in EPA/rush (-0.20) and success rate (39.8%), at least the Seahawks’ run game managed to keep the ball off the floor. I’d still caution against getting overly excited for Wilson’s outlook despite an RB6 finish (21-81-1; 3-39-1) — at 3.9 yards/rush and a 29% success rate in a “breakout”, my money’s still on Zach Charbonnet to secure as much work as he can handle upon returning.

• Start: RB Emanuel Wilson, WR Jaxon-Smith Njigba
• Sit: WR Rashid Shaheed, RB George Holani
• Sleeper: QB Sam Darnold, TE AJ Barner

Next Week's Bold Headline, Today

My crystal ball must be broken because every time I shake it, a different answer appears. Let’s call this one deadlocked at the end of regulation (+1200 at sportsbooks, by the way), and whoever makes the last big play gets the W. Count on one thing for sure — me planted on my couch watching every snap.
