Top 5 storylines to follow during Packers mandatory minicamp

4. Who takes the lead in the kicking competition before training camp?

The three-way competition at kicker is also must-watch. Green Bay is making second-year Anders Carlson earn a roster spot this summer by bringing in Jack Podlesny and veteran Greg Joseph. There's no denying Carlson's upside—he has a big leg and can make kicks from any distance—but that means nothing without consistency.

It's impossible to replicate the pressure of a real NFL game on the practice field, but the warning signs were there last summer. Carlson struggled for consistency throughout training camp. So far, he has taken a step to changing that.

The pressure is on all three kickers at minicamp. The Athletic's Matt Schneidman reported that they went 11 of 12 during a practice last week.

3. How does the defense look under Jeff Hafley?

Green Bay's defense is undergoing significant changes under new defensive coordinator Jeff Hafley. It is already evident how quickly the players have bought into his aggressive system, including starting nickel corner Keisean Nixon.

"He's competitive as hell. He goes at Matt LaFleur," cornerback Keisean Nixon told Up & Adams. "He brings the best out of us and we like playing for him, so his defense is ready to go."

Nixon added that Hafley isn't afraid to bring the heat against LaFleur's offense at practice, including an increase of blitzes on third down.

More pressure is a notable change we can expect to see under Hafley. It's good news for just about everyone in the starting lineup, including rookie linebacker Edgerrin Cooper, who made eight sacks as a blitzer in his final season at Texas A&M.

Other areas to watch include the rotation of the defensive backs, the preferred starting lineup, and the development of second-year players like Lukas Van Ness and Karl Brooks. The Packers' defense could take a massive step forward under Hafley, and this side of the ball is must-watch throughout minicamp.
