Surprisingly, most concussions reportedly occur in the trenches, with the OL and DL.
The solution was available in the mid 80s.
49ers offensive lineman, Steve Wallace wore a shell over his helmet. They called it a double helmet. The shell was painted to match the helmet and included the logo.
I believe a player for the Bill's also wore this in the 90s.
My prediction is that they revert back to something similar. Right or wrong, no matter what you think, the networks are going to have back door meetings about
how this looks, or would look, on television.
