With the increased speed in the game, better equipment needs to be worn. Players should wear kevlar long johns or hockey socks. They should also wear kevlar long sleeves that are held in place by a strap that goes between the thumb and fingers. And especially a kevlar high turtle-neck.
I hope this happens, and it isn't a player being killed or seriously permanently injured that forces these changes.
It's a disgrace that players get chirped for wearing neck guards. Reminds me of the old days when Dinosaur Don used to chirp players for wearing visors as Chicken Swedes or French guys hiding behind visors.
