4. Cameron Wake, LB, Miami Dolphins
Cameron Wake was brought in last year from the CFL but sat behind two former Pro Bowlers in Jason Taylor and Joey Porter. The 3-4 defense employed by the Dolphins needs sacks from its outside linebackers, specifically someone who can pick up the 16 sacks Porter and Taylor produced a year ago. With a rookie, Koa Misi, probably lining up on the opposite end, it is Wake's new role as the starter to be the pass rusher teams fear.
