2008-09: Patrick Koudys played Junior B hockey with the Welland Junior Canadians. Koudys, whose father played in the OHL, was selected in the 7th round of the OHL’s Priority draft by Oshawa.
2009-10: Koudys did not sign with Oshawa and played for the Junior A Burlington Cougars of the CCHL. In 50 games, Koudys scored 5 goals and added 28 assists for 33 points. In 12 playoff games, Koudys picked up 1 assist. Koudys originally committed to playing at RPI in 2011-12 but he and the Engineers’ staff felt his progress merited starting his college career a year earlier than planned.
2010-11: Koudys played in 31 games as a freshman at RPI. As part of an Engineers defense corps which featured three veterans including team captain John Kennedy, he scored 1 goal and added 2 assists for 3 points. Koudys was a late addition to the NHL Draft Combine and was ranked 76th amongst North American skaters by Central Scouting. He was selected by Washington in the 5th round (147th overall) of the 2011 NHL Draft.
2011-12: Koudys skated in 27 of 39 games for the Engineers and was a healthy scratch in 8 of the last 11 contests – including all five ECAC playoff games. Koudys scored 1 goal with 1 assist and was minus-eight with 22 penalty minutes. He decided to transfer to another school in the spring and will play in the USHL in 2012-13.
2012-13: Koudys returned to junior hockey after two seasons at RPI — skating for the USHL’s Muskegon Lumberjacks. In 64 games he scored 1 goal with 14 assists and was +9 with 95 penalty minutes. One season after finishing with the USHL’s second-worst record, Muskegon reached the playoffs after finishing fourth in the Eastern Conference. The Lumberjacks were swept by eventual Clark Cup champion Dubuque in a quarterfinal series. Koudys was +1 with no points nor penalty minutes in the three-game series. In November 2012 he committed to playing college hockey at Penn State in 2013-14.
2013-14: Koudys returned to college hockey — skating in 36 games for Penn State as a junior. He scored 2 goals with 6 assists and was -21 with 26 penalty minutes. Penn State, playing in its second season of varsity hockey, finished last in the six-team Big Ten Hockey Conference in the league’s first season. The Nittany Lions defeated Michigan 2-1 in double overtime in a conference quarterfinal game before falling to Wisconsin, 2-1, in the Big Ten semifinals.
2014-15: Koudys was a team captain for Penn State in his senior year.
Koudys has quality size at 6’2 and 190 pounds, though he does not play an overly physical game. Since being selected in the fifth round of the 2011 NHL Draft, he has developed into a defensively sound two-way defender. His focus has been on making the smart, sound defensive play. Offensively, he is very limited and his skating still needs work going forward. He also has potential leadership qualities in the future, having captained the Big Ten’s Penn State Nittany Lions as a senior in 2014-15.
Koudys was not tendered an entry-level from the Capitals prior to the 2015-16 season, becoming an unrestricted free agent. After attending training camp with the AHL's Rockford IceHogs he eventually signed an ECHL deal with the Indy Fuel. If he can refine his skating, Koudys has the chance to be a quality sixth/seventh defenseman who focuses predominantly on his own zone.
