Kyle Shanahan just finished his fourth double-digit-loss season in eight years. And now Fox Sports 1 Analyst Emmanuel Acho thinks Shanahan is on the hot seat.

The 49ers’ inability to close out three NFC West games still had Shanahan steaming after the season. They coughed up fourth-quarter leads in losses to the L.A. Rams (Weeks 3 and 15), the Cardinals in Week 5, and the Seahawks on Nov. 17.

The 49ers just made an interesting change to their offensive coaching staff. They promoted assistant passing game specialist Klay Kubiak to offensive coordinator. It's unclear how Kubiak's job will change.

The San Francisco 49ers are making an interesting change to their coaching staff. Head coach Kyle Shanahan on Wednesday in his end-of-season press conference told reporters offensive passing game

Show him the money? Shanahan had a strong quote about Brock Purdy, saying, "I plan on being with Brock here the whole time I'm here,”

The 49ers defensive scheme is somewhat outdated. They're still running the same defensive scheme that the Seahawks ran 10 years ago under head coach Pete Carroll. The Seahawks don't even run this scheme anymore.

Emmanuel Acho, LeSean McCoy, James Jones and Chase Daniel reflect on whether Kyle Shanahan is on the hot seat after the San Francisco 49ers fired defensive coordinator Nick Sorensen (Niners do wish for him to stay in another role) and special teams coordinator Brian Schneider.

The San Francisco 49ers aren't wasting time when it comes to finding a new defensive coordinator. On Tuesday night, Matt Maiocco of NBC Sports reported that Nick Sorensen will not return to the 49ers next season as their defensive coordinator.
