Well, quite literally they were on the same level of production with zero revisionist history needed...
Nelson - 65 TT 9 TFLs 5.5 sacks
Mathis - 48 TT 5 TFLs 3.5 sacks
Tannor - 43 TT 6 TFLs 2.5 sacks
Robinson - 37 12.5 TFLs 7 sacks
Hutmacher - 24 TT 4 TFLs 2 sacks
But since I think Nash and Ty did things that didn't necessarily garner stats from time to time I'll move on from that...
What I stated that you are arguing with me about is those players from 2022 that left I heard the exact same thing about. How they were going to be tough to replace and how our line wouldn't be able to hold up against the B1G OLs, yet Tony White managed to overcome it. Since you seem to be dumbfounded that the same conversation is being had now as was back then even though White made us better, here's a link to multiple articles stating how difficult it will be to fill the voids left by those guys and how thin the position group will be:
Departing Edge’s Garrett Nelson, Ochaun Mathis and Caleb Tannor, plus IDL Colton Feist, accounted for 27 of the team’s 60 TFL last year. That’s a lot of production to replace from a defense that ranked 125th in rushing success rate (52%) and a decrepit 129th in standard downs line yards per carry at 3.04. IDL Ty Robinson (6’6/310) is back, but questions remain about how well this front will hold up against the massive OLs the Big Ten schedule is going to throw at them. It’s fair to speculate how immediate DC White’s impact will be in that facet of the game considering Syracuse ranked 120th overall with a 50% rushing success rate after three years of White calling the D there.

Nelson's departure leaves a massive hole in the Husker defense, which lost its top three pass rushers – Nelson, Caleb Tannor and Ochaun Mathis – to the NFL.
Husker defensive star and captain Garrett Nelson will forgo a final season of college football at Nebraska and turn pro, he announced Tuesday on social media.

Worse; Pass rush
The Huskers must replace both Garrett Nelson and Ochaun Mathis at edge. The duo combined for 9 sacks and 14 TFL in 2022.
Blaine Gunnerson will get first crack at one of the edge spots. Veteran Ty Robinson provides depth on the inside and is good against the run.
Who else steps up? In the rugged B1G, Nebraska will need to find answers fast.
Nebraska should have better leadership and discipline with Matt Rhule at the helm, but depth may be an issue in Year 1.

The loss of Feist also means five of Nebraska’s top six defenders that produced quarterback pressures will not be back in 2023.
Ochaun Mathis(33 pressures), Nelson (32), Caleb Tannor (15), Feist (12) and Devin Drew (6) are all moving on. Robinson (24 pressures) is the only one in the top six returning.
Nebraska defensive lineman Colton Feist will not be back at Nebraska for a sixth season in 2023. It's another big blow to NU defense.
