Ok.
This brings back something that happened to me in grad school. I was looking at steady state enzymology, and the method used to solve for steady state rate equations. The method is straightforward and takes advantage of the mapping between enzyme species, the transformation between enzyme forms, and the mathematical concept of a graph. Enzyme species become vertices, the transformations are directed edges, and so you can apply all kinds of graph algorithms to the solution of these systems.
What happens if the number of enzyme species becomes large is that the resulting equation also becomes large and unmanageable without computer assistance. But the nature of the original equation that you solve to get your formulas is that it's a non homogenous linear equation. So, instead of solving for a forumula using this linear equation, you can simply plug numbers into each of the elements of the linear equation and solve numerically. I called this approach the "matrix method". I hadn't seen this in any literature on the subject so I got this algorithm (and 2 others) published in Computer Applications in the Biosciences, vol 1 number 2.
A month later I was reading the literature and found that a Professor Garfinkle of the University of Pennsylvania had used the technique in the past. It was clearly the same thing we had published so I told my prof and we had an addendum added to the journal stating that it was prior art and who had used it. The question wasn't one of theft; the question was one of proper accreditation. He was first. He deserves the credit.
There is a sloppy habit in the Internet world to engage in wholesale theft of ideas. I've seen posts of mine on alt.sports.football.pro.dallas-cowboys get lifted and published as someone else's work on the Eagles alt.sports board, published word for word. The guy who did it was a well known Cowboys troll there and when called out for his theft he pretended it didn't happen (The Eagles regulars there tore him a new one, I didn't need to do anything but point out the theft and give the links). When someone copies your stuff it has to be called out.
The problem here is that Gil's work is clearly a copy of the FO stuff. It shares the same quirky numerical errors as the FO stuff. That doesn't happen by accident. Some copying had to occur. It *doesn't matter* if Gil did or did not read the FO article. Someone who has been giving Gil numbers must have.
If they don't recant, Gil and NFL.com can be sued for plagiarism. It's really that simple. If Gil is as honest as people claim he is, he'll publish a notice of the prior work.
As far as my "matrix method" goes.. I saw at least 2 other people independently develop the exact same method over the years I was active in the sciences and they did not know about any prior work. Some ideas become "obvious" once the science reaches a certain stage and are independently invented over and over again as a function of necessity. But I don't think that's true in the Brandt case, because he wouldn't have copied the FO data errors. His numbers would have been true to some other paradigm, or had their own original quirks.
Idea theft in the sports world isn't new. If Moneyball can be believed, when the Elias Sports Bureau wrote their own books to counter what Bill James was doing in sabermetrics, their product stole many of Mr James' ideas while using their publication to insult him.
