The 49ers didn't have any 'Fat Guys' vs the Packers.
Bosa (2 Pro Bowls) the only starter with a Pro Bowl selection.
None of the starters have made All Pro at any point in their career (per wiki).

POS ….... %Snaps …...... HT …......... WT …............ Player

Is either Armstead or Jones better than Gallimore?
Armstead looks like a sane version of David Irving.
Is their #2 DE (Samson Ebukam) better than Gregory?
Yes, Bosa > DLaw
LOL, another offseason of our fans thinking the DL is just fine, we need to add a couple of low level FAs, maybe throw a mid round pick or two at a DL and we'll have a great DL.
49ers were 7th in rushing yards per game. Cowboys were 16th. 49ers were 5th in ypc. Cowboys were 25th. 49ers were 5th in sacks, Cowboys were 14th (and let's be honest, the Cowboys pass rush was only this good because of a LB they played at DE). Football Outsiders had the SF DL ranked 2nd in run D, the Cowboys 13th. They had the 49ers DL rating 5th against the pass, the Cowboys 14th.
If you go with PFF, yes Armstead and Jones are better than Gallimore. Gallimore had a rating of 50. Armstead had a 77 and Jones had a 73 grade.
There is zero doubt the 49ers have a better defensive front than we do. But you do this every year. You lay out how this position or that positoin or that group is not that bad or actually good and then the season happens, they are mediocre and you come back and try to defend them again in the next offseason. Wash, rinse, repeat.
