Nice random article on the net...unfortunately I don't see it as being very valuable. The reason is that a lot of his "analysis" is up to his selection of what is valuable. Also, the ones he selected are equal in value, but who is to say that yards per attemp is as important as passing TDs? And thirdly, he ranks anyone who is not in the top 10 at any of the chosen statistics as an 11, but what if a QB is REALLY bad at that statistic? What if the QB is last in the league, he still gets an 11. Which means consistant QBs accross all statistics that were subjectively chosen are penalized and volatile QBs at the statistics which the author has subjectively chosen are rewarded.
Basically, there are so many variables that are subjective to the author. I'm willing to be that I could create a similar study, where I pick the stats that are important and which are not, and how to rate them, where I put Wilson as the 20th best in the league and Brady as #1 or #2.
The more variables you have the less valuable any analysis is, especially if you subjectively decide on the value of those variables. It's kind of like saying (i admit in the extreme to prove a point), who is the best QB on the 2nd Sunday that is not on a full or quarter moon, while there are more above 500 teams playing other above 500 teams than 70% of other weeks, while I have not shaven for 3 days. There are so many variables which I have decided, that I can change those variables to other things and change the result. In some statistic circles I believe they are called "degrees of freedom." The less degrees of freedom (variables) you have, everything else staying constant, the more valuable the analysis is. The more variables you have, especially subjective variables, the less value the analysis has.
That's not to say Wilson isn't top 5, it's just to say this analysis isn't very valuable in my eyes.
