I discovered this site a couple days ago and it's addictive. It allows you to be TT and draft prospective Packer players through 7 rounds. The computer drafts for the other teams based on team needs and what "Big Board" you choose. (There are 7 or so Big Boards to choose from and what a difference depending on which one you choose.) It gives you a great prospective on what TT is faced with.
Great fun: http://fanspeak.com/ontheclock/
