However, the secondary's struggles became increasingly apparent, culminating in a playoff loss to the Seattle Seahawks, where the unit appeared to run out of steam. A closer examination of the numbers reveals why shoring up the back end of the defence must be a top priority heading into the new campaign under newly appointed DC Raheem Morris.
Last season, the 49ers ranked a disappointing 25th in the league, allowing an average of 232.4 passing yards per game. The overall defensive performance placed them 20th, with 340.2 total yards allowed per contest. Perhaps more concerning was the lack of playmaking in the secondary: San Francisco managed just six interceptions all season, ranking 29th in the NFL.
The pass rush, hampered significantly by Nick Bosa's prolonged absence and lack of depth at the position, could only muster 18 total sacks collectively—placing the team dead last at 32nd. The lack of a consistent pass rush left the secondary exposed, resulting in the unit surrendering the fourth-most yards per drive (34.7) in the league.
Talent and Depth Concerns
The secondary is anchored by standout corner Deommodore Lenoir, whose individual performances, ability, and willingness to travel and lock in on the opposing team's top receiving option have often kept the group afloat. Lenoir might not be a top-three or five corner in the league, but don't tell him that. His confidence appears never rattled, and he continues to show up play after play. Yet it's clear he cannot carry the burden alone.
Renardo Green, who has started opposite Lenoir, has found himself embroiled in trade rumors, possibly signaling the organization's search for an upgrade or added depth on the outside. Rookie Upton Stout emerged as a bright spot in the slot, showing promise in nickel packages.
At safety, the rotation of Ji'Ayir Brown, Marques Single, and Malik Mustapha displayed moments of high-level play. However, the group was plagued by inconsistency, with lapses in coverage and missed assignments contributing to the team's defensive woes. The lack of a steady, reliable presence at the back end only heightened the pressure on the corners, amplifying the secondary's vulnerability in key moments. I will never take for granted the former pair of Dashon Goldson and Donte Whitner that used to patrol the secondary and inflict pain on a regular basis.
Ultimately, the stats as a group mentioned above make it clear: improvement in the secondary is not just desirable; it is essential for the 49ers' aspirations next season. By addressing these critical areas, San Francisco can position itself as a true contender in the NFC once again.
