The Green Bay Packers' offense has sagged of late, scoring just 19.5 points per contest in the last four games, after averaging 32.0 to start the season.
"I feel like it's my fault," Cobb said, via ESPN.com. "I feel like it's on me. I've got to make more plays when I get opportunities."
Cobb struggled through an early-season shoulder injury, but hasn't missed a game. He also has lacked the explosive plays in recent weeks. In the past four games, Cobb hasn't broke 45 total yards receiving or scored a touchdown. In Week 8 he caught six passes -- most since Week 3 -- but averaged just 4.5 yards per catch.
The fifth-year pro has struggled to find separation and last week against Denver was unable to break away from defenders after the catch.
When asked how much tougher it's been for him without injured Jordy Nelson, Cobb sounded frustrated with the situation and question.
"I don't know what you want from me," he said after pausing for several seconds. "I don't know what you want to hear. I'm going to go out and I'm going to play better for this team. I'm going to do more. I'm going to be the best Randall I can be."
It's understandable that Cobb would be frustrated. He's a Pro Bowl talent who isn't playing up to his own standards. In truth, the lack of offensive production is system-wide and doesn't fall squarely on the wideout's shoulders.
