NFL Nation's Rob Demovsky examines the three biggest issues facing the Green Bay Packers heading into training camp:

Replacing Finley: The longer tight end Jermichael Finley remains unsigned, the more likely it appears his time in Green Bay -- and perhaps in the NFL -- is over, despite his desire to continue to play. The team's reluctance to clear Finley after last season's neck injury falls in line with its philosophy on similar injuries. Just last month, it cut ties with another player who suffered a neck injury last season, running back Johnathan Franklin. The Packers re-signed Andrew Quarless to a two-year, $3 million contract in March, but that's hardly starter's money. The door is open for rookie third-round draft pick Richard Rodgers, who performed well enough during the organized team activities and minicamp practices (which Quarless missed because of injury) to move into the starting spot. Rodgers has the kind of dynamic athletic ability that Finley brought to the position. The wild card there is Colt Lyerla, the undrafted but talented rookie from Oregon. Had Lyerla not left the Ducks' program and run into trouble subsequently last year, he might have been a high draft pick. The Packers also will have to assess whether Brandon Bostick can make a bigger impact than he did last season.

The safeties: We know the Packers used their first-round pick on safety Ha Ha Clinton-Dix. Now what? It's time to see whether the former Alabama standout can make an immediate impact. One thing was clear based on the offseason practices: Packers defensive coordinator Dom Capers is not going to hand the rookie a starting job. Unlike Morgan Burnett, who lined up as a starting safety from his first practice as a rookie in 2010, Clinton-Dix played mostly with the second-string defense in OTAs and minicamp. At some point, perhaps even when training camp opens, Capers will insert Clinton-Dix with the starters, and he may never relinquish that role. But the Packers believe they have options in case Clinton-Dix is not ready to start from the outset. Converted cornerback Micah Hyde took almost all of the reps alongside Burnett with the No. 1 defense this offseason, and coach Mike McCarthy would like to get Hyde on the field more often than just sub packages. Using him at safety, at the very least in the base defense, would be one way to accomplish that. The Packers also like third-year pro Sean Richardson, who has shown some playmaking ability.

Capers on the hot seat: With so much of the offseason focus on improving the defense -- from tweaks to the scheme, to changes on the coaching staff, to the addition of high-priced free-agent pass-rusher Julius Peppers, to another first-round pick on that side of the ball -- it's worth wondering what might happen if none of that equates to significant improvement on Capers' side of the ball. McCarthy spent more time than usual this offseason working with Capers on changes to the scheme. At the very least, that was an indication McCarthy was not happy with the direction the defense was headed, although it was not problematic enough for McCarthy to make a change at the position. He trusts Capers and his scheme, but clearly there were issues that troubled him. The Packers slipped from 11th overall in yards allowed in 2012 to 25th last season. Injuries hit Capers' unit hard last season, but McCarthy is not willing to use that as an excuse. Rather, he charged Capers with adjusting his scheme so that it will be more adaptable to plugging in players if injuries strike again.
