I searched for a draft do-over game but didn't find one.
Draft Do Over Game
List all players from the first round, as well as players from the second round and undrafted players who made it to the league. Then allow users to move two players either up or down one spot once per day. Run game for a week or so and see what the board thinks the draft should have looked like. I realize that this game has a large potential to be abused, i.e. Cook falling off the board completely, but it may be interesting to see where players SHOULD have ended up vs wher they did.
