Yes, but the problem with the injury bug is it’s not a real thing.
In reality if you have one starting safety out for the year and the other dealing with multiple injuries, then your backup safeties are at increased risk to be injured due to increased playing time.
They’re just as likely to get injured as the first two safeties contrary to what many fans around here seem to believe. If that happens you’re stuck with practice squad-level players on the back end in the playoffs.
If you had the knowledge of the starters’ injuries before the deadline and did nothing to bolster depth then it is by definition an epic fail
