Wait, who the f### do you think you are? I don't give a f### how new I am to the site, until proven otherwise, you're a tool.
What, it's a bad thing for individuals to buy the jersey of their favourite player even if the stint was for one season? I will let you in on a secret bro - the above scenario ain't so rare. I have a #13 from St Louis (home and away), NYG (home) and Arizona (home) with the name Warner on the back of it. Kill me.
You call it a waste of money, some call it money well spent. I have a "sports room" as such and each of those jerseys (with others! *shock* *horror*) adorn the wall framed.
If you can afford to do as above, who the f### are you to care and label someone a moron for doing so?
Tool.
