[8] Upon rejoining the Warriors, Schultz was selected to represent Team West at the 2008 World Junior A Challenge with whom he won a silver medal.

[1] In his freshman season with the Badgers, Schultz immediately made an impact on the team, alongside defensive partner Cody Goloubef, as he helped them become one of the conference's best power units.

[13] His play throughout the season helped lift the Badgers to the WCHA Final Five, the collective name for the quarterfinal, semifinal, and championship rounds.

As the Badgers began the season with a six-game winless streak, Schultz made an immediate impact on the ice by scoring a hat-trick in a 4–1 win over Michigan State in the College Hockey Showcase.

As he finished the season leading all defensemen in goals and points, Schultz became the first sophomore to be named Defensive Player of the Year in the Western Collegiate Hockey Association.

[22] Schultz remained true to his commitment and returned to the Badgers for the 2011–12 season despite confusion from hockey pundits and Anaheim Ducks staff.

[23] The Badgers squad for the 2011–12 season was the youngest under head coach Mike Eaves, as it was composed overwhelmingly of 11 sophomores and nine freshmen.

[26][27] The Badgers power play also improved as Schultz led all defensemen with nine goals and 28 points through 18 games, and ranked among the top three players in all of college hockey.

[30] Schultz eventually chose to remain with the Badgers and he was soon chosen for the 2012 All-CHN First Team in March after he led all defensemen with 16 goals, 44 points, and a 1.19 points-per-game scoring average.

[48] During the 2013 offseason, the Oilers added more defencemen to their roster including Andrew Ference, Philip Larsen, Anton Belov, and Darnell Nurse.

[49] Schultz returned to the Oilers for the 2013–14 season where he set new career-highs in goals, assists, and points through 74 games in the final year of his contract.

[54] Schultz struggled on the power play during the coaching tenure of Eakins but improved as the Oilers’ hired Todd Nelson in January 2015.

[59] He was specifically recruited by head coach Mike Sullivan due to his offensive talents, speed, and strong breakouts of the defensive zone.

[61] He eventually made his debut with the team on March 6 against the New Jersey Devils, playing on the third defensive pair with Ian Cole.

[67] He continued to provide offence from the third pair with Ian Cole[68] but also saw time on the power play with Sidney Crosby, Evgeni Malkin, and Phil Kessel.

[68] On the third defensive pair with Cole in Game 1, Schultz played nearly 19 minutes of ice time and earned a primary assist on the Penguins’ opening goal.

[72] At the beginning of the season, Schultz immediately stepped back into the first power-play unit role where he averaged over 27 shot attempts per 60 minutes of power play time through five games.

[75] Through December, Schultz also became the lone defenseman on the Penguins power play unit,[76] a role which he continued even after Letang returned to the lineup.

[79] While Schultz, Letang, Trevor Daley, and Määttä were recovering from injuries, the Penguins added Ron Hainsey to help their depleted defence.

[95] In the first year of his contract, Schultz failed to replicate his previous seasons' scoring prowess due to injuries and illnesses.

[97] Upon his return, head coach Mike Sullivan placed Schultz back into the Penguins top power-play unit with Letang.

[98] He continued to make an impact in the lineup and quickly accumulated seven more points before suffering a lower-body injury in a December game against the New York Rangers.

[110] One week after his return, he scored his first goal of the season and played over 30 minutes in the 2019 NHL Stadium Series overtime loss to the Flyers.

[111] During the Stadium Series, defencemen Letang and Brian Dumoulin suffered long term injuries leading to coach Sullivan to rely more heavily on Schultz, Jack Johnson, Chad Ruhwedel, and Marcus Pettersson.

[115] Once the regular season began, Schultz impressed coaching staff as he led all Penguins defencemen in power-play points through mid-October.

[1] During the 2020 Stanley Cup qualifiers, Schultz and Jack Johnson struggled as the third defensive pair and they were on the ice for the majority of the Montreal Canadiens' ten goals throughout the series.

[127] As the season progressed, Schultz began a mainstay on the second pair with Dmitry Orlov and had quickly accumulated two goals and 15 assists through 30 games by late March.

[134] Schultz finished the regular season with four goals and 19 assists for 23 points through 74 games[1] while playing on the third pairing alongside Trevor van Riemsdyk.

[141] During the Kraken's second round series against the Dallas Stars, Schultz helped set a franchise records for fastest three goals to start a playoff game.

[146] After failing to secure a contract in the NHL,[147] on October 23, 2024, Schultz signed with HC Lugano for the remainder of the 2024–25 National League season.
