I think I know what you are talking about. It's where you have a salary of say 1,000,000 and each player has a predetermined 'salary'.
You then build your team based on who you like. You can choose anyone you want but have to stay under the 1,000,000 cap Tom Brady costs, say 200,000, you now have 800,000 left to spend on other guys. You then have to fill up a certain number of positions.
Does this sound familiar? If so, go to any newsstand, and flip thru a fantasy football magazine. I have seen full page ads for this this year in a number of magazines. Not sure of the specific ones tho.
