On the analysis side is The Heisman Pundit. The Heisman Pundit is an LA based blogger who makes his living by sifting through the mess of sportscasting, and presenting them to his readers in a nice, easy on the eyes, method of analysis.
And on the predictive side is StiffArmTrophy.com. This site has predicted the Heisman Winner, and the order of the finalists, every year since the site's inception in 2002. If you want to look like Nostradamus to your friends, this is the site to check just before the trophy is awarded.
Stick to these two sites and you'll never be out of the loop.
