Having played the game for years, I can assure you the impact being generated on the line is very real. These folks do interact with their body/arms, but head on head contact is a very real part of the game, and that is the part that really affects the brain.

And the part of soccer that seems to cause concern is heading the ball, not the running around part.

Comparing helmet to helmet impacts to skiing over rough terrain feels like a real stretch here.

But we don't know what the concern is in soccer. Heading is immediately looked at because it's an impact, but the actual cause may be something altogether different.

I mentioned the g forces measured in skiing elsewhere. They are absolutely in the range of subconcussion.
