because, again, your projection is assuming that all these kids will have access to college. They won't.
For those that won't, having someone successful tell them that the path to that success means working hard to achieve is something to be promoted.
You have him lumped in with folks that are on record saying "practice? practice?" and a bunch of others who don't work hard, tell everyone they don't work hard and are openly combative with the very organizations that allowed them their success. (or worse, in the case of vick, jones, et al).
We're not talking about an absolute criteria. If we had our choice of who these kids looked up to, I am with you that my first choice would NOT be from athletics. We don't get that choice...and given a choice of ANY athlete of color to put in front of these kids I'm likely to pick Tiger. He's extremely talented YET he still works harder than anyone with half his game and he promotes a high calibre message to kids about goal setting.
Your stated position that he's no better than any other black athlete is simply wrong.
