They can pick up a decent free agent Safety.
Again, if they intend to keep Tyrod, they have to have a running game that can dominate, week to week, regardless of injuries. Good running backs can step right in as rookies.
Gillislee is "good", they need 2 excellent backs, because one will likely be hobbled for half the games.
One of the first 3 picks should be a RB, and if a really good prospect is there in the 1st, take him. I know that goes against common drafting philosophies, but this offense isn't built around a passing QB.
