Sorry I am a dope...
I should have thought that not everyone might know what I was talking about...
Its just another way to build your fantasy team. Basically you use an auction to build your team instead of a draft and you only bid on players that you want. Each team has a salary cap that you cannot go over.
For example I want pujols for my team I start the bidding for him obviously at least 3 or 4 owners will want him so you get into a bidding war for him, whoever bids the highest for the player gets him. If you paid 50 bucks for him and your cap is $100 you have to fill out the rest of your team for the remaining $50 you have under the cap. Does that make sense??? not then
It gives everyone a fair shot at the best plyers unlike a draft...
