2010-11: Chase Lang skated for the Pursuit of Excellence program in British Columbia. He was selected by the Calgary Hitmen in the fifth round (89th overall) of the 2011 WHL Bantam Draft.
2011-12: Lang appeared in five games with the junior A Alberni Valley Bulldogs in the BCHL as a 15-year-old and was the leading scorer for the North Island Silvertips midget major team. He had no points nor penalties skating with the Bulldogs. Lang scored 29 goals with 32 assists and had 52 penalty minutes in 40 games for North Island. The Silvertips finished seventh in the BC midget league — three points out of the playoffs.
2012-13: Lang saw limited ice time with Calgary in his first WHL season — skating in 44 of 72 regular season games. He scored 4 goals with 7 assists and was -2 with 10 penalty minutes. The Hitmen finished second in the Central Division and lost to Edmonton in the Eastern Conference Finals. A healthy scratch for much of the playoffs, Lang made his debut in the second round series against Red Deer after an injury to Pavlo Padakin and was -1 with no points nor penalties in five playoff games.
2013-14: Lang skated in 68 regular season games for Calgary in his second season; providing secondary scoring and physical two-way play as the Hitmen finished first in the Central Division. He scored 10 goals with 15 assists and was +13 with 52 penalty minutes. Calgary was upset by Kootenay in the first round of the playoffs with Lang recording 3 assists and finishing -1 with 13 penalty minutes in the six-game series. Not among the 210 North American skaters in the Central Scouting final rankings, he was selected by Minnesota in the sixth round (167th overall) in the 2014 NHL Draft.
2014-15: Lang attended his first training camp with the Minnesota Wild before being returned to the WHL’s Calgary Hitmen. Playing in 63 of 72 games for the Hitmen in the regular season, he scored 25 goals with 31 assists and was +16 with 61 penalty minutes. Calgary finished first in the Central Division and reached the Eastern Conference finals against Brandon. Lang was hampered by a lower-body injury in the playoffs, missing seven games. He scored 4 goals with 3 assists and was +6 with 10 penalty minutes.
2015-16: Lang made his pro hockey debut in March, joining Wild AHL affiliate Iowa on an amateur tryout contract following his fourth WHL season. He scored 2 goals with 1 assist and was -4 with 4 penalty minutes in 11 games with Iowa. Lang was returned to Calgary following his second NHL training camp with the Wild. He skated in 14 games with the Hitmen before being acquired by the Vancouver Giants at the end of October as part of a multi-player trade. Lang scored 27 goals with 36 assists and was -10 with 76 penalty minutes in 69 regular season games between the two teams. Vancouver missed the WHL playoffs, finishing last in the B.C. Division.
Lang is a bit light and not overly gifted offensively but is a smart, responsible center who can play in any role. While he has been a consistent scorer in the WHL, his skill set does not suggest he will be a big-time offensive player but rather the type of player who does a lot of things well and is defensively aware.
Lang was the rebuilding Vancouver Giants' second-leading scorer in 2015-16 after being acquired from the Calgary Hitmen in an early season trade. One of the few WHL veterans on a team with several 17 and 18-year-olds, he gained a new experience after playing on some dominant Calgary teams. Drafted by Minnesota in 2014, he has yet to sign an entry-level contract with the Wild and would re-enter the 2016 NHL Draft if not signed before then. The Wild got an extended look at Lang when he skated for the AHL's Iowa Wild at the end of the year. His play in the WHL suggests Lang can be a two-way forward with a responsible defensive game.
