Earning a C+ Contract Value Index, Isaac Guerendo's 4-year pact reflects how the San Francisco 49ers valued the position market at the fourth-round stage of the 2024 draft. At $1.18M AAV on a rookie scale deal, the contract itself is team-friendly and carries minimal financial risk — the real problem is that Guerendo's on-field performance hasn't justified even that modest investment. In the 2025 season, he logged 14 games but accumulated only 4 tackles, a statistical footprint so thin it underscores why the 49ers have pivoted away from him as a viable contributor. The team's offseason activity tells the story: the organization drafted a higher-upside prospect at the position, signed a veteran alternative, and cycled through multiple roster moves that collectively signal no confidence in the 25-year-old second-year player. His 15 career receptions represent the kind of developmental dead-end that gives a front office every rational reason to move on, especially with a 91-day runway to camp and a crowded backfield already assembled. Unless catastrophic injuries strike, Guerendo enters the preseason in precarious standing — a player on borrowed time whose thin statistical résumé and organization's clear pivot make him one of the most vulnerable roster casualties in the NFC heading into September.
Other same-position deals the Contract Value Index also places in the C band — a quick read on where Isaac's contract sits relative to comparable money.
Stacked against the RB field, Isaac Guerendo grades out at a C performance level for San Francisco. A second-year player drafted in the fourth round (2024, pick 129), Guerendo appeared in 14 games during the 2025 season but managed just 4 tackles—production that barely registers as a depth contribution on either side of the ball, let alone as a viable rotational back. His thinnest statistical footprint relative to opportunity is his career reception total of 15, a number that underscores he has not carved out any meaningful role in the passing game, a critical liability in modern NFL run-game schemes. Durability is not the issue—he stayed healthy enough to see the field across 14 contests—but what he did with those snaps falls well short of second-year development expectations. The 49ers' offseason activity paints the clearest picture: adding a third-round pick (Kaelon Black), signing veteran Brian Robinson Jr., and cycling through backup signing-and-release moves with Jermar Jefferson, Sincere McCormick, and Elijah Mitchell all but confirms the organization has moved on from Guerendo as a contributor. With his rookie scale contract offering minimal financial leverage and a pectoral tear forcing him into late-camp recovery, Guerendo enters training camp fighting to justify his roster spot in what amounts to a make-or-break preseason for a player whose organizational goodwill has been thoroughly depleted.
Isaac Guerendo ranks 69th of 175 graded running backs by performance. That slots Isaac between Jordan Waters (C+) just ahead and Nathan Carter (C) just behind.

Nathan CarterAtlanta FalconsIsaac Guerendo's public perception has cratered to about as low as it gets for a player still technically on a roster, and the narrative surrounding the 25-year-old running back reflects an organization that has quietly moved on. The media framing is unambiguous: multiple outlets have characterized his situation as "borrowed time," with his roster spot described as being in serious jeopardy heading into the 2026 season — language that signals not speculation but near-consensus. That framing aligns painfully well with his on-field production grade, which sits at a D, underscoring that Guerendo has not done enough in his two seasons as a fourth-round pick to build any organizational goodwill as a buffer against roster pressure. The 49ers have done nothing to quiet the noise — drafting Kaelon Black in the third round and bringing in veteran Brian Robinson Jr. are moves that collectively constitute a clear vote of no confidence, and the team's broader offseason activity, including the signing of Sincere McCormick, further crowds a backfield that apparently has no room for Guerendo. His 15 career receptions represent the kind of thin statistical footprint that gives a front office every reason to cut ties without hesitation. Unless the injury bug strikes San Francisco's backfield in a significant way between now and the regular season opener, the prevailing analyst consensus is that Guerendo is one of the most vulnerable camp roster casualties in the NFC — a second-year player whose window to establish himself has effectively closed.
