Personally, I think just the opposite. The fact that it’s NOT a big deal, that Russell Wilson isn’t a “black QB”, he’s just a QB, is a good thing. I remember hearing a little bit about how he was only the second, and it was a bit surprising, but it’s just not that big of a deal.
Also, a bit oddly, it seems that a lot of times, “black QB” isn’t just refering to a black man who is playing QB, but refers to a particular style of QB, notably one who are dangerous scrambling threats. RGIII, Kaepernick, Vick, McNabb are “black QBs”. Hell, I’ve even heard Tim Tebow refered to, on more than one ocassion, as a “white black QB”, which sounds odd, but I knew what they meant. In that regard, though Russell Wilson can run, his style isn’t the same. Fortunately, it seems like that usage has quickly fallen out of favor in the last few years with more black men playing the position that don’t fit that mold and they’re just scrambling quarterbacks or running threats or whatever.
Anyway, back on the topic more directly. I would also agree with the idea that Russell Wilson didn’t lead his team to the Super Bowl, at least not in the same way that Peyton Manning did. Russell Wilson is a serviceable quarterback who did his job well, but in the same way, you don’t hear about Trent Dilfer leading the 2000 Ravens or Brad Johnson leading the 2002 Buccaneers to their respective Super Bowl wins, but you hear plenty about the likes of Peyton Manning, Tom Brady, Drew Brees, etc. Also considering that he was playing against one like Peyton Manning, coming off one of the best years any quarterback has ever had and his team flounders like it did, it’s going to steal some of his thunder. Thus, that it’s worked out that way, I think has little or nothing to do with race and would be virtually the same if he wasn’t black.
