2010-11: Nedomlel made his WHL debut with the Swift Current Broncos after a couple of years in the lower Czech junior leagues. The hulking blueliner posted 10 assists and was minus-15 with 107 penalty minutes in 66 games. Swift Current missed the playoffs after finishing with the WHL's second-worst record. Not among the 212 North American skaters in Central Scouting's final rankings, Nedomlel was selected by Detroit in the sixth round (175th overall) of the 2011 NHL Draft.
2011-12: Nedomlel returned to Swift Current for his second WHL season after going to camp with the Red Wings and displayed an offensive component to his game to go along with his physical play. One of two players to skate in all 72 games for the Broncos, he scored 10 goals with 36 assists and was minus-35 with 83 penalty minutes. Swift Current finished fifth in the six-team East Division, missing the WHL playoffs.
2012-13: Nedomlel was the second-leading scorer amongst Swift Current defensemen in his third WHL season. An assistant captain, he scored 7 goals with 21 assists and was -13; finishing second on the Broncos with 105 penalty minutes. Swift Current finished third in the East Division and reached the playoffs for the first time in three seasons. Nedomlel had 1 assist and was -2 with 2 penalty minutes in the five-game series with Calgary. He signed a three-year entry-level contract with Detroit in April, 2013.
Nedomlel is not going to quarterback your powerplay or thrill you with an end to end rush anytime soon. He is a big, mean, physical stay at home defenseman who isn’t afraid to drop the gloves and who doesn’t lose when he decides to. While he may have little offensive upside, he provides a steady, physical, defensive presence on the back end.
Nedomlel's defensive development continued in 2012-13, and he earned both a new contract with Detroit and a spot on the Grand Rapids Griffins' AHL roster in 2013-14.
