Writeup on Shazier, a common pick for the Packers in the mocks. http://nfl.si.com/2014/04/11/2014-nf...immy-jernigan/

Conclusion: One of the most obvious NFL trends over the last few years is the linebacker who can play at several positions, and is light and fast enough to have an impact in a 360-degree sense. More and more, teams are sacrificing the old model of the linebacker in favor of those athletes who can do everything from run support to flex tight end coverage. Shazier is a prime example of that paradigm, and this should put him at the precipice of the first round, if not higher. There are power and strength issues here, but unless you somehow happen to land the 2000 version of Ray Lewis, you’re generally going to have to sacrifice something in the equation. Shazier said at the combine that his style compares to that of Tampa Bay’s Lavonte David, but I’ll go with Bobby Wagner, as I believe Shazier has a bit more pop to his game.
Would not replace Hawk as the absorber of the Guard or FB block, but would close a lot of holes. Also could work as nickel and dime backer. Since he can pass rush, you could use him in multiple places in different formations.
