Green Bay Packers: Full Position Breakdown, Depth-Chart Analysis at Quarterback

The Green Bay Packers currently have four players on the roster at quarterback: Aaron Rodgers, veteran backup Scott Tolzien, fifth-round rookie Brett Hundley and University of Wisconsin-Whitewater product Matt Blanchard, signed in April.

Given Rodgers' recent injuries—his broken collarbone in 2013 and his calf tear in 2014—and the struggles the offense endured when the Packers weren't prepared for his absence, Green Bay will likely carry three quarterbacks on the 53-man roster in 2015: Rodgers, Tolzien, and Hundley. 

We know what Rodgers' ceiling is (or is his best still yet to come?) and what he brings to the team, but let's break down what the position as a whole looks like and how Tolzien and Hundley could contribute. 

First String: Aaron Rodgers

Rodgers, both statistically and given the depth of talent around him on offense, is primed to have one of the best seasons of his career in 2015. 

In 2014, playing injured at the end of the season, Rodgers threw for the most yards (4,381) since his record-setting 2011 season and a career-low five interceptions.

His completion percentage of 65.6 percent last season, the lowest it's been since 2009, was likely affected by his injuries. 

But everything is in place around Rodgers to enable his success. All five of Green Bay's starting offensive linemen from last season will return in 2015, and the line will in fact be intact until 2017 at least. Rodgers took only 28 sacks in 2014, much lower than his career average of 36 as a starter. 

In addition to his top weapons, Jordy Nelson and Randall Cobb, Rodgers also has promising young options in Davante Adams, Jared Abbrederis, Jeff Janis and 2015 rookie Ty Montgomery. 

Second String: Scott Tolzien

The Packers signed Tolzien to a one-year prove-it deal this offseason, finally promoting him to the No. 2 spot behind Rodgers by declining to re-sign veteran backup Matt Flynn in free agency. 

Tolzien didn't see any action in 2014. In 2013, with Rodgers out for seven games, Tolzien started two games and played in three, posting a stat line for the season of 55 completions, with a 61.1 percent completion rate, one touchdown and five interceptions.

It wasn't a stellar outing. But Green Bay had just promoted Tolzien from the practice squad, and he didn't even know the playbook that well.

He remained the No. 3 quarterback behind Flynn in 2014, but the Packers demonstrated a confidence in Tolzien's continued development when they let Flynn walk in free agency and re-signed the 27-year-old. Now he will have had two training camps to continue learning the playbook combined with an arm strength that always surpassed Flynn's.

Head coach Mike McCarthy demonstrated satisfaction with Tolzien's continued development at the NFL combine in February.

"I think Scott is definitely an ascending player," McCarthy said, per Weston Hodkiewicz of the Green Bay Press-Gazette. "I still think he has more growth in front of him." 

However, now Tolzien once again has competition for the No. 2 spot behind Rodgers—in the form of rookie Hundley. 

Third String: Brett Hundley

Though he praised Tolzien at the NFL combine, McCarthy also dropped hints that Green Bay would look to draft a quarterback in 2015. That it did, trading up in Round 5 to select UCLA's Hundley. 

"I don't think you ever pass on a quarterback," McCarthy had said at the combine, per Rob Reischel of the Milwaukee Journal Sentinel. "It's the most important position in the game. If you have one at a value that you're comfortable and he's in a position to pick him, I think you pick him."

Hundley's value as a fifth-round pick was obvious. CBSSports.com projected him to be drafted in Round 2, and he's a player who could have handled starting for a team this year but instead will be groomed in McCarthy's quarterback school, the same one that helped refine Rodgers. 

"I was shocked," Packers director of player personnel Eliot Wolf said of Hundley's fall, per Ryan Wood of the Green Bay Press-Gazette. 

Per Wood, McCarthy is intrigued by Hundley's raw talent. "Brett has a ton of that," McCarthy said. "He's a tough guy. That stands out. He's athletic."

Hundley left UCLA as the all-time leader in passing, with 11,713 total yards, 75 touchdown passes and 25 interceptions.

His talent could allow him to push Tolzien for the No. 2 spot behind Rodgers and give him the chance to work with the scout team this year. However, expect Tolzien's experience to give him an edge...for now. Training camp will be very interesting to watch with these two players vying for the chance to back up Rodgers.
