With Czechia trailing 2-1, Ottawa Senators prospect Tomas Hamara threw a puck toward the net that Kos was able to deflect past goaltender Thomas Milic to make it 2-2. With the action then shifting to 3-on-3 in overtime, Dylan Guenther scored the golden goal to win it for Canada.
Selected in the sixth round (184th overall) of the 2021 NHL Draft, Kos wasn't the only Florida Panther prospect representing Czechia at the best-on-best U20 international tournament. Marek Alscher, a third-round pick (93rd overall) in 2022, was also there, but did not suit up.
Leaving Nova Scotia with their heads held high, the Czechs not only captured their first medal since taking home bronze back in 2005, but also played for gold for the first time since 2001.
"The whole team gives us that motivation,"
Kos told IIHF.com after the gold-medal game
. "Everybody knows that we have that thing in our team, that we can do everything. I've said many times, I'm so proud of this team and for the whole team. Of course, the players are on the ice, but people don't see the other people who care about the team. So I would like to thank everybody."
