Why? If say there are 20 picks in a row that are roughly equal, and latter in the draft there are spots like that. And team a trades up to get the 1st of the 20, but gives up 2 of the 20 to get it, and then gets a player 10 spots latter that is clearly out of the tier. Then the team receiving the 2 players in the group of 20 clearly wins out.
When you say that though, you are assuming you know exactly who will be selected where. You don't know this. Obviously there are some perceived dropoffs here and there, and some "clumps" here and there, but generally, the value differential from 1st-11th is huge compared to the difference between 11th-21st, which is greater than the difference between 21st-31st... and so on. By the time you get to 211-221 and 221-231 and so on, you could consider the differences almost negligible. The earlier in the draft you are, the more pronounced it generally gets.
