DL Arik Armstead
Armstead has been sensational in his fifth season, and he has the opportunity Sunday to help spearhead a big-time defensive effort. Not only will he be vital in getting pressure on Rodgers as an interior pass rusher, but he has to have a good game setting the edge against the run. The Packers may try and stress the 49ers horizontally by pounding the edges early with quick throws and outside runs. Armstead staying outside and slowing those plays before they can get north to south, then getting penetration as a pass rusher inside are two things that can really slow Green Bay’s offense.
