I think they should "redesign" the helmets, and prevent injuries like Little got-- with some modifications. If you'll notice the sides of the hockey helmet are flat and go "around" the ear -- like over and above. This is likely done to let the player hear properly. The ear area is totally exposed, as well as the head area around the ear. Actually I think the ears stick out from the sides of the helmet -- if I'm not mistaken.
My idea would be to have the ear area totally covered -- sort of like a football helmet, but with a good sized whole in it. to allow for proper hearing. If a puck was to hit you in the ear area, it would just hit hard plastic, that is elevated --over and out from the ear. This is something that should be done, and could save somebody else's career or life maybe. They could name the new helmet design the Little Helmet. I'm not joking around hear, shots coming in at 90 miles per hour, on a totally exposed ear area could kill you.
I know it's not common to get hit in the side of the head -- but my idea on a helmet redesign should maybe be implemented. They didn't start wearing Goalie masks until plenty of Goalies took heavy pucks to the face, and hundreds of stitches, and the Goalie mask when thru many design changes unto what we have today -- "very smart."
