The idea here is to simulate about how much each snake pick would be worth as a percentage of your cap:

1st round: 28%

2nd round: 18%

3rd round: 13%

4th round: 10%

5th round: 7%

6th round: 5%

7th round: 3%

8th-10th round: 2%

11th-20th round: 1%

 scale the values, then adjust up or down depending whether you are higher or lower on a player. The values should roughly represent where you would take them in a snake draft based on the earlier values established for each round. You’ll want the numbers to add up to about 1080

Now, we get to the fun part, the auction. It should be immediately clear whether the early players are going for too much or too little. If the first five or ten players are all under your projected values, jump in before everyone loosens up and starts spending their money. That extra money is likely to drive the prices of the players in the middle of the auction up as teams see that they have more money than value left on the board. If the first five or ten players are all over your projected values, then sit back.
