Well if you look at the NFL.com top teams (by points) we rank 13th (62k) at around and the Reskins are 11th (81k fans). I do this by points because it shows willings towards activity.
So I say we will miss it by about 22%.
Though, when ESPN was doing the ROTY POLL that wilson was winning, we were killing it for everyone outside of the US. If we could find some way to employ the rest of the world to help us out.... (Seriously, the rest of the World represented about 33% of all votes cast).
Edit: I should have calculated all the people that don't like the Redskins (5%) weighted by the people that don't like the hawks (49'ers). Should make it more like 17%
