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.
Isaac Guerendo is a second-year running back for the San Francisco 49ers who has appeared in 30 career games, establishing him as a developing contributor rather than an established starter at his position. The Louisville product has carved out a modest role in the team's backfield, accumulating 420 rushing yards and four touchdowns on the ground while adding 15 receptions for 152 yards, operating primarily as a complementary piece in San Francisco's run-heavy offensive scheme. His durability profile remains a concern, as his limited games played through two seasons suggest he hasn't yet proven the consistency and health reliability necessary to shoulder a workhorse load in the NFL. What Guerendo brings to the 49ers is versatility and effort—his willingness to contribute on special teams and in the passing game provides depth in a crowded backfield, though his production grades out as average relative to his position peers. The key to Guerendo's trajectory will be whether he can stay healthy and accumulate the game experience needed to develop into a reliable two-down back; at this stage, he remains very much a player whose future role depends on the team's depth needs and his ability to command more offensive opportunities.
Isaac Guerendo ranks 67th of 173 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.
