Disagree. They aren't far off but they need more than just "one safety". Their LBs are average. Actually, as of right now they only have one decent one to begin with. That one being the young guy, Jenkins I think is his name. Even then, last year was his breakout season. Next to him they have Koa Misi (who's always been average at best), Trusnik (role player) and Sheppard. Yes, that Sheppard. Wouldn't surprise me if they draft a couple this year.
If we put together an O-Line that can generate any sort of push in the run game against the Fish, I don't see there being a problem with Suh's arrival. He's only one guy. And oddly enough - Wake never really shows up against us. At least not since the 2012 season.
