Did you fail to read the "two testing centers determined that the masks offer similar protection" part of the story. HSM are similar to traditional masks in protection from foul balls, at least straight on. The obvious indisputable part is that they offer protection on the top and sides unlike traditional masks.
I feel bad for Matheny and I thought the article to be a good read...

At any rate it seems that I am wiser than he is to this small extent, that I do not think that I know what I do not know. ~Socrates
