So I have a personalized jersey myself and just want to say some things.
There was a deal at the Garden a few years back (2007) where you could get 50% off jerseys if you brought in your old ones. Well, I had quite a few ones from when I was a kid, literally a few youth smalls. So I took my sisters to a game and we all got jerseys, from what I recall came out to $50 bucks or so a pop including a season-ticket membership discount from a friend. They got Dubi, Callahan, Avery and I decided to get myself one with my nickname as I already had a Lundqvist. This was after I told all of them to get Lundqvist, yet they didn't.
We all went to a game a few weeks ago, none of them wore their jerseys but I had mine, and they all said, "Yeah we should have listened." Do I think I'm "cool" with my personalized jersey, no. I feel as though it is better to represent the team on the front of jersey, rather than whomever is on the back of it.
I don't think that my nickname on the back of the jersey is such a big deal as it is made out to be. Some people buy jerseys for collections, some buy blanks because they don't want to waste $ on a player's name, other don't even bother buying jerseys. As long as we are all supporting the same team, it shouldn't matter regardless of what you are paying or not paying for.
