It's only natural to root a little harder for those that you can relate to... or did you think Eminem's absurd amount of sales were based solely on his talent?
If you're Chinese, there's nothing wrong with saying you rooted for Yao Ming to become the player he is today in the NBA because he's Chinese like you are. And the Chinese love Yao... just like the Argentinans love Ginobili, the Germans love Nowitzki, etc. You have something in common with the player, and so you feel they represent that which you have in common.
If you're a University of Wisconsin alum, chances are you rooted for guys like Ron Dayne, Chris Chambers, Lee Evans, or Jamar Fletcher after NFL teams drafted them. Again... you have something in common with the player, and so you feel they represent that which you have in common.
The very same principle generally applies to race/ethnicity in sports, no matter how PC you choose to be about it. There's nothing wrong with it, in my opinion... I had a couple of Asian friends in high school who would occasionally watch Cowboys games with me just so they could watch Dat Nguyen play.
Successful white WRs are a rare enough commodity in the NFL nowadays, and so I wouldn't put
any fault at a white fan for rooting Danny on because of what they have in common. They're just doing what fans of sport all over the world do when they notice a player there is something significant shared between themselves and that player.
Oh, back to the topic...
Because 1) there's nothing else to freak over right now, and 2) amidst all the talk/hype about our backup WRs all offseason, few remember that our backup WRs only caught 24 balls total last year (for the NFL's 2nd best offense) and are generally not a big part of our offense.
The backups should all be healthy again in a month or so, T.O. and Crayton will do what they do, we'll get off to a quick start, and assuming one of the starting WRs doesn't get hurt during the next month... all of the whining will prove to be much ado about nothing.
