Let's lump all these folks into one thread.  Not all of them are past NFL players, though a chunk of them are (Steve Gleason, Tim Shaw, OJ Brigance, etc).  Lest we forget the Pete Frates of the world, Jason Becker or even Stephen Hawking (though he's covered plenty elsewhere), or the late Sam Shepard.  Not every affliction needs it's own thread, but this one is pretty well-defined and the progression easy enough to follow.

And with that, a Tim Shaw update.  He looks good enough, not even in a wheelchair at this point, so I think we can give him a pass to 2019 before we need to check in on him.
