The NFL preseason is coming to a close, but trading season is just heating up. Several reports in recent weeks claimed the Commanders were shopping Brian Robinson Jr. Now, Washington has finally found a suitor. On Friday afternoon, the running back was traded the 49ers in exchange for a sixth-round pick, per ESPN’s Adam Schefter.
The move, while rumored for weeks, comes as a shock. The Commanders, fresh off of their best season in decades, have their eyes set on a Super Bowl. Trading away a quality running back doesn’t seem to align with those goals. The 49ers, another NFC contender, already have a superstar rusher in Christian McCaffrey. In a now-crowded San Francisco backfield, what does this trade mean for fantasy football managers? Let’s break down what to expect from B-Rob and his Niners teammates this season.
Fantasy Football Impact: Brian Robinson Jr.
We’ll start with the man himself, who appeared destined to be moved. The Commanders seem confident in their running back room, led by veteran Austin Ekeler. As a result, Robinson Jr. was deemed expendable by Washington’s front office. Still, it’s not as if the Alabama alum is just another guy. Over 14 games last season, he ran for 799 yards and nine touchdowns, forming a dynamic duo with quarterback Jayden Daniels. Over three seasons in the NFL, the 25-year-old has averaged 4.1 yards per carry and 71.1 yards from scrimmage.
In half-PPR formats, Robinson Jr. finished as the RB28 in points per game last season (RB31 in PPR). That’s not eye-popping, but he was a reliable flex option in most 12-team leagues. It’s difficult to see that being the case once again this year. McCaffrey remains one of the sport’s most dominant backs, even after an injury-plagued 2024-25 campaign. Regardless, head coach Kyle Shanahan is one of the NFL’s brightest offensive minds. It’s not unrealistic to think he’ll scheme up some plays every week for his newest weapon.
For now, Robinson Jr. doesn’t appear to be much more than a high-end backup. Still, in a league as physically demanding as the NFL, he’s only an injury away from fantasy relevance. If McCaffrey is sidelined, Robinson Jr. would be in an even better position than his Commanders tenure. Until that occurs, he’s not someone managers in most leagues can put in their starting lineups.
Fantasy Football Impact: Christian McCaffrey
Let’s shift focus to a potential Hall of Famer in Christian McCaffrey. As previously mentioned, the former Offensive Player of the Year remains an elite running back. However, his recent health isn’t something that can be ignored. Since 2020, CMC has suited up for only 47 of a potential 84 games (55.9%). He looked like a shell of himself last season, accumulating 348 total yards over four outings. In the past, McCaffrey has alternated between injury-prone and healthy seasons. Still, at 29 years of age, nothing is guaranteed.
It’s difficult to say that the trade will have a major impact on CMC’s fantasy stock. After all, we’re only two years removed from his historic 2023 season. If anything, this move is smart roster management by the 49ers. For a club looking to contend, putting all your faith in a running back’s health is foolish. By acquiring an over-qualified backup, San Francisco now has the perfect insurance option. There might be a few less touches for McCaffrey, but he’s still a set-it and forget-it RB1…when healthy. Grabbing Robinson Jr. in the later rounds of your fantasy drafts to pair with the veteran might be prudent.
Fantasy Football Impact: Isaac Guerendo
If anyone is the biggest loser in this trade, it’s Isaac Guerendo. Due to an epidemic of 49ers injuries last season, the fourth-round pick was thrust into a major role. All things considered, the rookie performed admirably. Over 16 games, the 25-year-old accumulated 572 yards from scrimmage and four touchdowns. That included a stellar 78-yard, two-TD performance in Week 14 vs. the Bears. With fellow backup Jordan Mason now in Minnesota, the assumption was that Guerendo was San Francisco’s RB2.
Now that Robinson Jr. has arrived, it’s difficult to envision many snaps for the second-year pro. Granted, Shanahan has a knack for getting every member of the roster involved in some fashion. However, that doesn’t mean much for fantasy purposes. Unless McCaffrey gets injured, Guerendo isn’t someone worth rostering, even in deep leagues. Should CMC go down, the Louisville alum is worth a speculative pickup. Still, it’s not as if he’ll suddenly become a fantasy starter. Add it all up, and the odds are stacked against this young rusher in 2025.
