Bill Huber at Scout.com says Randall in the lead for dime back job.
http://www.scout.com/nfl/packers/story/1570733Randall has made a play or two at every practice to vault ahead of second-round pick Quinten Rollins, who had a strong offseason but missed the first three practices of training camp due to his hamstring. Randall has joined Shields, Hayward and Hyde in the dime.
Should also note Randall has played both outside spots. Rollins hasn't yet, he's been inside at slot CB.
