Randall Cobb could become the next member of the Green Bay Packers' offense to sign an extension.
"I don't believe I've done enough," Cobb said Sunday, "and I think that's on me."
Cobb, 23, is entering the final season of the rookie contract he signed in 2011 after the Packers picked him in the second round. He had a breakout season in 2012, when he caught 80 passes for 954 yards and eight touchdowns.
