In this weekly, training-camp feature, we take a look at two on-the-bubble players trying to make the Packers roster: one whose poor play has him on the hot seat, asking his agent to start calling other teams; and another whose recent accomplishments have him getting comfy, feeling like he may be paying a few more months’ rent in Green Bay.

Hot seat: DE Jarius Wynn. Regressive, third-year CB Sam Shields has been the whipping boy throughout training camp and is a candidate for the hot seat. But, for now, we’ll leave him alone. Second-year WR Diondre Borel, a raw, undrafted talent who was stashed on the practice squad last year, is another worthy nominee after he fumbled a kick return and ran a poor route in the preseason opener. But even those players don’t face the uphill battle that Wynn has. 

A four-year Packers veteran, Wynn had three sacks last year, tied for the high on a hugely disappointing defensive line. The Packers used the offseason to upgrade that position, signing three free agents and drafting two rookies, in the hope of building some semblance of a pass rush. Suddenly, Wynn, who’s never been a factor in the run game, was at the bottom of the totem pole and hasn’t moved up since. He’s getting only a handful of reps in practice and did nothing in the Chargers game. Wynn’s always been an extremely hard worker and a good guy (he wore a Santa Claus suit -- with beard -- in the locker room after the Packers’ Christmas Day win over the Bears last year), but his time is running out in Green Bay and his gift this year may be under some other team’s tree. 

Assuming the Packers again keep six defensive linemen on the 53-man roster, there are already four locks (veterans B.J. Raji and Ryan Pickett and rookies Jerel Worthy and Mike Daniels). After that, newcomer Daniel Muir and reliable holdover C.J. Wilson seem to be firmly ahead of Wynn. And after that, the Packers will have to account for the fact that halfway through the regular season they will have two more defensive linemen on the team. Mike Neal, a 2010 second-round pick, is suspended four games, and Anthony Hargrove, an ebullient free-agent acquisition, is suspended eight games. Those two don’t count against the 53-man limit until they are eligible to play, but you can bet the Packers will keep their returns in mind when choosing which and how many players to keep at various positions.  

Getting comfy: LB Dezman Moses. A cyclone of energy and effort, Moses has demonstrated since June minicamp that he has serious pass-rush ability. The potential is evident from the practice field in the undrafted rookie from Tulane. In the preseason opener at San Diego, though, Moses splayed well and produced in an NFL game. 

Based on his impressive work throughout training camp, Moses was playing with the No. 1 defense on the game's opening series, having replaced Clay Matthews after five plays. Although he had two official tackles, one was a tag-team effort with Rob Francois to stop a Chargers RB for a 1-yard gain, and the other was a penetrating, punt-coverage tackle on special teams that brought the returner down after five yards. 

Besides his work ethic and raw rushing talent, Moses has this going for him: The Packers are not shy about having undrafted and unknown players on the roster at OLB, as long as they turn heads. In the past two years, the team has put three undrafted, training-camp OLBs on the regular-season roster (Frank Zombo in 2010, Vic So’oto and Jamari Lattimore in 2011). At that position, if you can show an extraordinary ability to rush the QB, you’ve got a shot at a spot. Moses has a shot.
