Excellent decision. I'm glad he got to skate around a little bit in April or May during P-Bruins practice for morale, and I'm glad he's hung up the skates and gloves.
He'd make a great columnist - certainly better than one particular columnist who imagines himself the best sportswriter there ever was, and whose articles I actively avoid on the net. Robins would also be great doing background "slice-of-a-player's-life" pieces, if that's where his interests lie. His blog on addiction to chewing tobacco is a raw, visceral, and even heartbreaking story to read - something you really wouldn't expect.
I'm most glad that Robins has options, and seems inclined to use every one of them to the best of his abilities. A lot of NHLers who go through TBI/PCS don't have anything to fall back on. I don't know what kind of support system the NHL has, or how good the players are using that support, but this is a case where more is always better.
