It might not exactly be a must-win yet, but the San Francisco 49ers cannot afford another ill-advised performance.
The 49ers enter Week 4 with a 1-2 record, which isn't terrible, given their injury circumstances, but still poor, given the context of their most recent loss.
San Francisco suffered an embarrassing double-digit collapse to the Los Angeles Rams. Instead of putting its NFC West rivals at 0-3, the 49ers now are at the bottom of the NFC West.

Of course, there's still plenty of time to right the ship. San Francisco under Kyle Shanahan has shown it can embark on runs entering the playoffs, but nothing is guaranteed in the NFL.
Up next are the 1-2 New England Patriots -- led by veteran quarterback Jacoby Brissett and first-time coach Jerod Mayo -- at home, a potential "get right" opponent if the 49ers don't take them lightly.
