I think those are the areas. On a typical roster - WR's about 10, DL about 16, RBs about 5-6, TE's about 6. OL and DB may also have take a haircut.
Since we don't have an IR we don't cut injured players. I think there are a few guys who may have long term injury and recovery. you also are not cutting the incoming FR. This almost guarantees we will be cutting players who have been talked about as being key backups.
It is also possible that they seek to recruit from the portal, which would increase the number of cuts.
