TG ran a faster 40 than most of the non-white RBs at the combine and historically as well. Fat lards like Lendale White get drafted early when they have minimal work ethic and were surrounded by greats.
Even if there was any merit in your argument (there isn’t), you are doing a very poor job at presenting it because Vince Young/JaMarcus Russell/and even Mike Vick are jokes at the QB position relative to the rest of the NFL. Just terrible QBs. Great athletes and ‘playmakers’ I suppose, but they are not great leaders or quarterbacks by any means and were all drafted significantly higher than Tebow with lesser accolades.
