What basis does Stolarz have to make this assertion?
If you ask ChatGPT:
when playing ice hockey would a puck travelling at 70 miles per hour that hits a goalie square in the mask have enough force to create a concussion
You may get this answer
Yes, a puck traveling at 70 miles per hour (about 113 km/h) striking a goalie square in the mask can potentially cause a concussion, even with modern goalie masks.
Here's why:
High kinetic energy: A standard hockey puck weighs about 6 ounces (170 grams). At 70 mph, it carries over 200 joules of kinetic energy — roughly equivalent to being hit in the head with a hard-thrown baseball or a strong punch.
Modern goalie masks do a good job of spreading out impact forces and absorbing energy, but they are not perfect. The mask can:
Flex or deform slightly under impact.
Transmit vibrations and acceleration to the head and brain.
Cause the head to jerk backward suddenly (rotational acceleration is a major cause of concussions).
Concussions happen not just from direct impact, but from rapid acceleration or deceleration of the brain inside the skull. Even without the puck breaking through the mask, that sudden jolt can be enough.
Real-world context:
Many professional goalies have suffered concussions from pucks hitting their masks — even at lower speeds than 70 mph.
NHL goalie masks are required to meet high standards, but no equipment can fully prevent concussions in all scenarios.
Summary:
Yes, a 70 mph puck striking a goalie in the mask can generate enough force to cause a concussion, depending on the angle, mask quality, impact location, and the individual's tolerance.
