That matches my eye test that a huge amount of the pressures and sacks are on Fields. There is a reason the sack rate drops dramatically when he has been hurt and a backup has played. And the phenomenon was the same when he was at OSU. Before his years as the starter OSU was among the best in the country at preventing sacks and it was the same after when Stroud was there. Yet when Fields was the QB they allowed a ton of sacks. OSU didn't suddenly have much worse offensive lines during that period either (their starting OL from 2020 included a 2nd round pick, 2 3rd round picks, and then their other tackle was also drafted into the NFL and 2019 you had 3 of those same starters plus a 3rd round pick).
