2008-09: Czerwonka scored 16 goals in 55 games for the Kootenay Ice (WHL) as a 16-year-old. He also had two assists and was -10 with 83 PMs (including ten fights) as the Ice finished third in their division and reached the playoffs. Czerwonka was scoreless and -2 with 5 PMs in the Ice's four-game playoff series with Brandon.
2009-10: Czerwonka skated in 54 of 72 games for Kootenay in his second season in the WHL and was third on the team with 106 PMs, including 11 fights. He scored 4 goals with 9 assists and was -5 on an Ice team that finished second in its division before falling to Medicine Hat in a six-game first round playoff series. Czerwonka scored 1 goal with 2 assists and was -1 with 9 PMs in the playoffs. Not listed among the 210 North American skaters in Central Scouting's final rankings, he was selected by the Oilers in the sixth round (166th overall) of the 2010 NHL Draft.
2010-11: Czerwonka emerged as a play-making, two-way energy forward in his third WHL season as Kootenay advanced to the Memorial Cup after winning the WHL playoff championship. In 68 regular season games he scored 13 goals with 30 assists and cut down on the penalty minutes (78); finishing +9 as the Ice finished third in their division. Czerwonka skated in 13 of 19 games during the playoffs, missing much of the first round series with a shoulder injury, and scored 2 goals with 3 assists with a -2 plus/minus and just 4 PMs. In five Memorial Cup games he scored 1 goal with 2 assists and was an even plus/minus with 6 PMs.
A physical player, Czerwonka isn't afraid to lay the big hit, work in the corners, and stand up for himself or his teammates. He has excellent leadership qualities and his combination of hard work and willingness to go to the dirty areas of the ice has seen him emerge as solid scorer at the WHL level, however it is highly unlikely he will bring much offense at the next level. He's the kind of hard working, jack of all trades, energy player that often fills the unsung hero role at the pro level.
Currently playing his fourth full WHL season, Czerwonka is a good bet to turn pro next season but may need to start in the ECHL due to the depth ahead of him. He's a longshot for an NHL career, however if he makes it, he will be playing the role of bottom six energy player.
