It’s amazing how small things can lead to upgrades, expensive or otherwise. I discovered media streaming to televisions over the summer, via the product ps3mediaserver, and that led to an interest in things like mplayer, ffmpeg, and avidemux. The demands of programs like that led to a motherboard upgrade, so now I have a 8 core AMD processor and 16 Gb of memory on my main desktop. Since 32 bit operating systems cannot address more than 4 GB at a time (though interestingly, the modern 32 bit pae kernels can handle 16 Gb of memory via paging tricks), I upgraded my main machine to Ubuntu 12.04, 64 bit.
Some notes: for those of you following my work technically, I’ll note that Maggie Xiong’s PDL::Stats does not like the version of PDL installed by Ubuntu 12.04 – that PDL is buggy – and CPAN does a poor job of trying to install PDL. It is best is to download the PDL module separately from CPAN and manually compile it. For one, you’re bound to find things you forgot to install and those extras will help give you a working product. Afterwards, you can compile PDL::Stats just fine.
John Turney, of the Pro Football Researcher’s Association, writes the blog about this article:
Shurmur ran an Eagle defense with the LA Rams and it was a double eagle defense, with 2 3-techs over the guards and a noseguard who was a linebacker by trade. The Eagle defense of Shurmur was very similar or identical to the 46.
Shumur’s book makes it clear, Eagle: The 5 LBer defense.
The only difference was in the personnel used. He used a linebacker in the place of the nose tackle and the defense ends. That allowed him to move that nose linebacker around if he wanted to and stem that guy to a standup linebacker and a variant of the Eagle called “Hawk”.
Shurmur did use a 3-4 as a base defense for Rams from 1983-90, but the Eagle was a sub defense they used for several reasons more often in 1988-90 than in 1985-87. In base situations with the Rams they were a 3-4 team. When the Eagle happened they’d pull the nose tackle Alvin Wright and LDE Doug Reed, and bring in extra linebackers to fill the spots in the Eagle.
So, the Eagle was an “eagle” and Shumur addresses this in his book. It was based on the Greasy Neale defense as well as the Buddy Ryan defense.
Thank you, John, for the correction. And for those of us who follow the Duece on Twitter, he tweeted an article from Strong Football about the Shurmer 5 LB defense, that pretty much lays out what John said above. That article is highly recommended. To borrow a diagram from that article, there is a position called nose backer, and he can be roughly where the Will backer is in a classic 4-3, or he can step into the line and function as a lightweight nose tackle.

Pretty cool, huh? At this point, I’d have to say that the Strong Football article is a must read for those of us interested in Eagle variants.
Stepping back to the beginning of preseason, there are at least two teams in the NFC East with lingering offensive line issues. I don’t have much insight presently into the state of the Giants or Redskins lines (feel free to speak up if you do), but you can see a fair amount of tweets and articles involving Philadelphia Eagle left tackle Demetress Bell. With the Cowboys, everyone who was considered a solution at guard (here, here, and here) and center, as of a couple months ago, is now injured. Guard has become something of a revolving door, and there is now talk of bringing in a veteran center, as Phil Costa is also injured.
