How about Jamarcus Russell? Or David Garrard? Or Tavarius Jackson? Or Vince Young? There never has been and never will be a black QB in the NFL who can perform at a level high enough to lift their team to win the Super Bowl. Doug Williams was not the typical black QB (he was a pocket passer) and only made it to the Super Bowl because it was a strike season.
42 Super Bowls, one black QB winner. Coincidence?
I do not believe race has any thing to do with it.
Nothing!
Given how few black QBs there have been it is a coincidence. It’s a simple function of math, with 32 teams, 7 year long average career, and 1 winner a year most QBs will never win a ring. There’ve been plenty of great black QBs, but it takes a lot more than a great QB to win an SB, in fact Trent Dilfer proves you don’t even need a great QB to win an SB. If you put any of the guys you mention in place of Dilfer the Ravens still get a ring.
