It appears that not only the genes of intensity, but facial genes are shared by a Super Bowl-winning head coach and an Olympic curler.
Superior, Wisconsin's John Shuster is leading the Team USA men's curling squad through a series of must-win matches to qualify for the medal rounds in the Pyeongchang Winter Olympics.
When looking at him screaming to his teammates after releasing the rock to slide down the Pyeongchang ice, it seems that his facial expressions look incredibly similar to that of Baltimore Ravens coach John Harbaugh. (You can see them above.)
No, they aren't really separated at birth, since Harbaugh (55 years old) is technically old enough to be Shuster's dad (35).
Screams are the life of both a curler and a coach on gameday, and other coaches seem to have facial similarity to the screaming Shuster.
For example: Harbaugh's brother Jim, the often-volatile head football coach at the University of Michigan.
And, Marquette men's basketball coach Steve Wojciechowski.

Which ones look the most alike? Seemingly John Harbaugh. But you can be the judge.
