Hey guys...need some help here. We're changing one of our keeper leagues from a snake draft to an auction draft. Now that it's an auction draft, we can no longer keep players and forfeit that round's pick like we used to for our snake draft. So we plan on basing the prices that is costs to keep a player based on last year's average auction price listed in 3 different sources (web sites, magazines, etc). Going forward, it will be based on how much they went for in our auction, but obviously this isn't a choice for this draft since last year was a snake draft.
Does anyone know of a few good sites (or magazines) to find auction prices for LAST YEAR? Thanks.
