Mike Tanier, in this week's Walkthrough on Football Outsiders asks, "What Do I Know?"
It's an interesting and useful question. Because really, what separates Tanier from the rest of us? The ability and willingness to sit down and immerse himself in football for hours on end, and then share what he's learned with us. Tanier makes the point that he's only got a 5-10% advantage over the rest of us in his ability to research information and spit it back to us.
Indeed, he says, "Anyone could do this, by being a committed researcher." Like, say, John Morgan, who's made the leap from "anonymous blogger" to "dedicated and informed commenter" by some serious research and football-watching. And all the better for us, who get to read his great commentary.
Just watch out, John. The next guy's looking over your shoulder, and he's got the tools to be you.
