1. Randall Cobb vs. Kyle Fuller – There's no guarantee Fuller gets the matchup against Cobb in the slot, but who can forget Cobb nearly breaking Fuller's ankles with that open-field move last season in Chicago. After catching a TD pass, Cobb dropped a couple of passes last week at Minnesota and has a history of making up for rough outings.
2. Mike Daniels vs. Patrick Omameh/Matt Slauson – Daniels will line up at times over either Bears guard, and the Packers' stout, strong interior lineman has been an unsung hero on Green Bay's defense. He was one of several key players who helped shut down Adrian Peterson last Sunday.
3. Eddie Lacy vs. Shea McClellin – The Bears moved McClellin, a former first-round pick and outside linebacker, to the inside, so it's a good bet Lacy will see him in the hole on several occasions. Can he make him miss? Will he drop the pads or spin? Lacy needs to make last Sunday's performance the rule and not the exception in 2015.
4. JC Tretter vs. Eddie Goldman – Tretter played well at center in place of Corey Linsley against the Vikings, and while at the time of this posting, Linsley hasn't been ruled out vs. the Bears, it may be tough for him to come back on a short week. Tretter held his own against Minnesota's Linval Joseph in the middle of the action last week, and Goldman is a rookie second-round pick with a lot of promise.
5. Jeff Janis vs. Robbie Gould – With Ty Montgomery out and Micah Hyde banged up, the kickoff return job could fall to Janis, whose 70-yard return against the Vikings was the Packers' longest in almost two years. Gould and the Bears' coverage teams could have their hands full against the Division II speedster.
