Interestingly enough...Evans graded out as one of the Packers top 5 performances by PFF. I've never really followed their ratings in the past so I can't comment on how they are calculated...just passing along the info.
TOP 5 GRADES:
Edge Nick Perry, 89.8 overall grade
LB Blake Martinez, 87.0 overall grade
DI Mike Daniels, 86.6 overall grade
WR Jordy Nelson, 81.8 overall grade
RG Jahri Evans, 79.1 overall grade
