San Francisco 49ers cut ties with new playmaker weeks after signing; what happened?

The San Francisco 49ers have quickly moved on from running back Jordan Mims, waiving him less than two weeks after signing and re-signing Sincere McCormick on a one-year deal. This roster shuffle underscores the team’s ongoing evaluation of depth behind top back Christian McCaffrey, with McCormick returning to provide experienced depth after a short May waiver stint for Mims. Mims’ brief tenure followed an offseason period that also included Jermar Jefferson’s brief signing and showcases the 49ers’ method of testing multiple options in camp to determine the best fit for their RB room.

Mims, a Fresno State product with NFL experience in Buffalo, New Orleans, and Tennessee, carried a strong college résumé but limited NFL impact. The move aligns with San Francisco’s roster math: prioritize players who can contribute on special teams, pass protection, and as practice options, rather than relying on a single unproven back. Mims’ departure after missing initial training camp signals that the team is prioritizing other depth options and keeping lines open for further adjustments.

Key takeaways:
– The 49ers replaced Jordan Mims with Sincere McCormick, signaling ongoing depth-chart experiments behind Christian McCaffrey.
– Mims’ NFL track record and Fresno State production explain why multiple teams showed continued interest, though he didn’t secure a longer-term spot.
– The back-end of the RB room remains unsettled, with San Francisco likely to continue evaluating and rotating options through training camp and the offseason.
