One of my favorite sites that I used to become well prepared for my fantasy football draft was Rotoworld.com. It is a great site because it has up to the minute information about players. Looking through their injury report was very helpful before the draft. I was able to know exactly who was hurt and for how long. Also they have great rankings and cheat sheets for your draft needs.
Not only is it great for fantasy football but it has great information for all sports. You're able to have all the important information at your finger tips to check on your favorite team and sport. I like it a little more than sites like ESPN.com because often you get stories and articles mixed. If i want just news and information rotoworld is the way to go.
