FAAB should use a second price or vickrey auction
Right now there's too much guessing about which other managers are going to bid on a player. A second-price auction feature would allow managers to bid their true values without needing to worry about that.
Roman Smith commented
A Vickrey auction system (popularized by Ebay) reduces the winning bid to $1 above the 2nd highest bid. Other fantasy platforms have started integrating this option, please make it available for the 2020 season.
