He didn't grow up in the greatest environment, so he never really had the chance to show how far he could get.
disagree.. he had a chance to fly right out of the hood into stardom, but he himself blew it (unfortunately).
can't blame environment in this case imo, some people just aren't driven, and that has nothing to do with environment.. he was "blessed" (lmao) with insane genetic ability, but he just didn't have the desire or drive to take it to the next level.. which means, he simply did not love track & field enough to make it his life. no matter how crappy your environment, if you love something with everything you have, then you won't let "stupid crap" come into your life to take it away from you: this means not hanging out with the wrong people, staying away from weed, trying to at least make avg grades, etc....
he didn't love it enough, which is understandable, it came easy for him..
