The defense allowed back-to-back drives of 12 and 14 plays in the fourth quarter that allowed Kyler Murray and the Cardinals turn a 23-13 deficit into a 24-23 win, marking the third time in the last six games for the 49ers starting at last season's Super Bowl that they lost a game that they led by double digits.

Students of recent history can recall the San Franscisco 49ers in 2021 seemingly out of the picture at 3-5 and then somehow rallying to reach the NFC Championship Game. A check of the game book from that day shows 17 players who were on the 49ers then and are on the 49ers now,

This is a troubling trend. The 49ers had a 13-point lead this Sunday against the Arizona Cardinals. Just a few weeks ago, the 49ers had a 14-point lead against the Rams and lost. No one finds ways to blow double-digit leads quite like Kyle Shanahan.
