The NFL Talking Heads talk a lot about drafting value, drafting players with a good history of data so you know what to expect. One of the tools that are helpful in your draft research is VBD (Value Based Drafting) for fantasy football. This is where you take how many players will be selected at each position and determine how much better each person is before the last player at a position is selected. By doing this, you can measure the “value” of one player vs another player at a different position. This might help you determine which player you should select in the middle of a draft by seeing if one player is more valuable to their position.
The NFL Talking Heads have gone ahead and created a sheet for you to use, you can access this at the Talking Heads Nation.
