Saw that Butch Goring is auctioning of a bunch of stuff (rings, jerseys, mini-Cups, etc...I'm assuming he's the one putting most, if not all, of those items up). Funny, I guess it does get to a point where, as much as we fans might think of these items as sacred entities, to former players, it all eventually just becomes "stuff" that's taking up space and is no longer special (of course, it could be something as simple as "I need money!"). I guess it probably reaches a point where, for some of these guys, if they ever had a room where they had a "shroud" set up with their trophies, maybe a framed jersey or two and some other memorabilia, one day they just look at it all and say "Man, I'm not that guy anymore, what am I really trying to prove with all of this stuff on display, I'm an old man now!" If it's between a closet and making some money off it, I can see why some former athletes start selling this stuff off...it's still hard for me to picture, but then again I'll never be in their shoes.
In Stan's case (and maybe I'm speculating here), he is 80+ years old and if his family doesn't want to keep the memorabilia it probably makes more sense for him to sell stuff now and get money to leave them instead of rings that don't mean much to them anyway.
