To be perfectly honest, there's some faith that goes into mocking Cyprien at the 26th pick. There's also a reason why UCLA defensive end Datone Jones isn't the selection here.
For starters, you hope that Cyprien's meteoric rise up boards is slightly more media based than NFL reality, and that clubs still view him as a late first-rounder. This is a deep draft for safeties, and teams could certainly have their boards situated in a way that allows Cyprien to be available at No. 26.
And why not Jones?
Simple. While safety is one of the deeper positions in this draft, the amount of impact defensive linemen (that fit a 3-4, mind you) suddenly becomes scarce once the big names (Sharrif Floyd, Star Lotulelei, etc.) are off the board. That's expected to happen before the 26th pick. Considering Jones is scheme-versatile and oozing potential, he could hear his name called well before the Packers are on the clock. Jones is a fit for a number of teams, but especially Indianapolis at No. 24.
Cyprien—if he's still around—is an easy fit for the Packers.
Not only is safety arguably the team's second biggest need (behind a difference-making 5-technique), but Cyprien is the kind of versatile (can play free and strong safety), tough and rangy player who can finally start replacing what Nick Collins left behind when he suffered a career-ending injury in 2011.
At his very best, Cyprien is a more athletic Dashon Goldson with a hint of Brian Dawkins. He's that good. The Packers could feel very confident in getting an immediate difference-maker with Cyprien in the first round.
