I actually wrote an article about this very subject before this season began. It stemmed from Pete Prisco idiotically saying that Thomas should in "no way" go into the Hall.
Here it is: http://phinaticism.blogspot.com/2007/07/zach-thomas-hall-of-fame-player.html
There's no two ways around it: Zach Thomas must be inducted into the Hall.
In my article I go beyond comparing him to Lewis and Urlacher and actually favorably compare him to the last MLB inducted into the Hall - Mike Singletary.
Check it out.
Nice Article and I was going to point out the very things you did in your write up. I debated this very thing with several friends, if Ray Lewis goes in, there is no way Zach can not. Period.
