If Maye/McDougald/Davis all stay healthy, I don't think there's that much of a drop off at safety for us.
Obviously the loss of Adams limits what Gregg Williams was doing with safeties in the box last season, but Ashtyn Davis is a very versatile player too. He isn't as good against the run at Jamal, no one in the NFL is. But Davis lined up at linebacker at Cal and is a sure-tackler.
McDougald is no slouch either.
