I can only imagine that most of today's players would have difficulty even signing their full name in the first place. They're so used to crapping out those "glyphs" they call signatures, and now they have to somehow insert their middle name in there? Seems like it would completely change things up for most of them, and I would bet that more than a few would flat out refuse rather than go to the extra trouble. Old-time players or those with signatures that are actually legible might be more amenable since it wouldn't require them to somehow alter that "logo" they call a signature.
Then again, they could just as easily add another squiggle and say, "There you go, now that's my full name," and who could say otherwise?
