The 2012 first-rounder has been running opposite Clay Matthews in OTAs. Perry is blaming his lost rookie season on his wrist injury. "We strike and we do everything with our hands," Perry said. "Without hands you don't have any grip to keep force and do all the things you're supposed to do with both hands. Makes you a little handicapped out there." Perry also says he's lost a little weight after playing at 265 last season. "I want to feel more comfortable where I'm at."

Restricted free agent Sam Shields is staying away from OTAs, and Tramon Williams is on the spot after back-to-back inconsistent seasons. A revelation as a rookie, Hayward led Green Bay in pass breakups (21) and interceptions (6), operating as the slot corner in nickel packages. He should start this year.

He'll likely miss the entire season. Tretter signed his contract just 11 days ago. A left tackle in college, Tretter was projected to contribute at center and guard. His rookie year will now amount to a "redshirt" campaign.

Williams' 2013 goal is to replace Charles Woodson in the secondary leadership role. To be taken seriously by teammates, he's going to have to keep his starting job -- a position the Packers opened to competition. Getting the shoulder right is a good first step. Williams has been a disappointment the past two years.

This assumes Boykin beats out rookies Charles Johnson and Kevin Dorsey. Rodgers sounds confident he will. "Behind (Randall Cobb, Jordy Nelson, and James Jones), I like what Jarrett Boykin brings," Rodgers said at OTAs. "He's a big, physical receiver who's going to get some opportunities." Packers "No. 4" receivers to open the year seemingly always pop on the fantasy radar in-season.

Jolly completed a drug treatment program Wednesday, the final step as he attempts an NFL comeback. He hasn't played since 2009, when he was 16-game starter who proceeded to get caught up in multiple drug arrests. Now 30, Jolly will not be guaranteed a roster spot after being out the league for three seasons.

Cobb caught 80 passes last year despite losing some reps to Greg Jennings and resting during Week 17. Now Jennings is gone and Rodgers is counting on Cobb to emerge further. "He can clean up certain areas and be even more fundamentally sound and be even more productive," Rodgers said. As one of the game's most dynamic slot receivers playing in an ideal offensive scheme, Cobb is going to be a PPR monster in fantasy circles.
