When Did This Happen?

Actually, the title of this story would more accurately be "Why Did This Happen?" I'm not the most observant of people and perhaps I've missed the discussion. So, what's the story with Ryan O'Reilly ditching the visor? Radar has looked terrific on the ice all year, but I just noticed last night that he's no longer wearing the shield he sported all last year.

I checked back and it looks like he made the change on the east coast trip. He was wearing one in the 3rd game against Detroit, but two days later he was going without against the Devils (shown above). It only took me 7 games to notice. Brilliant.

At any rate, has this been discussed somewhere? Clearly, I have missed it.
