I agree that seattles secondary is better, but everyone says the 49ers secondary is bad but I would argue they are average to good.
Charvarious Ward- very solid player. Plays under the radar as did not have a lot of INTs but allows a low completion % PFF 83.2. 1 INT 59% completion
Lenoir - shaky start to season, but played excellent in playoffs . 1 INT PFF 55.9.72%

completion percentage. 2 INT in playoffs, 38% completion percentage. This is the big question , do they get regular season Lenoir or playoff Lenoir
Tashon Gipson took Jimmie Wards job from him last year . 5 INTs . PFF 67.2. 57% completion
Talanoa Hufanga - huge splash plays at the start of of the season leading to all pro , trailed off late season 4 INT PFF 68 63% completion
Seattle by comparison
Tariq Woolen PFF 71.6 6 INT. 56% completion percentage. Spectacular rookie who should be better this year
Devon Witherspoon rookie . 2022 college 3 INTs 36% completion percentage
Quandre Diggs 4 INTs PFF 73.4 48 % completion percentage . A top NFL safety
Jamal Adams . Is he playing? 2021 2 INTs PFF 60.1 58% completion percentage
They may have been better with sticking with Ryan Neal PFF 85.6 60% completion percentage , 1 INT
