Matthew and Brady Tkachuk and J.T. Miller discussed in a group chat the three fights they ended up getting into in the first nine seconds of Team USA’s win over Canada during the teams’ first matchup in the 4 Nations Face-Off.

Matthew and Brady Tkachuk have been playing against one another in the NHL since the latter was drafted in 2018. Their father, Keith, played in the NHL for 18 years, retiring in 2010, and never was able to hoist the Stanley Cup.

BOSTON -- Keith Tkachuk sat in the stands at Bell Centre in Montreal on Saturday -- lower bowl, in the corner, about 20 rows from the ice. Together with wife Chantal, daughter Taryn and the other U.S. families, he felt the energy of the sellout crowd of 21,105 before the United States took on Canada.
