3 Safety looks 2017??

With Byrd being release i was curious does anyone believe that we will still be running 3 safety nickel sets as base defense similar to last year.

One should see that Byrd,Vaccaro (minus 4 game suspension) and Bell were starters for majority of season. I remember Bell playing well but made a few bad decisions at deep safety, and Vaccaro had a Horrible year playing deep safety with rob ryan. I feel we are trying to mimic the rams defense with Vaccaro playing the SS/SOLB position similar to Mark Barron, I could be way off base. We have not signed another SOLB or a true FS to roam middle. Thoughts, Draft maybe? Have faith in the many CBs injured to return and Bell is permanant FS?
