I thought you'd like to see today's version of a draft value chart instead of the one Jimmy Johnson created since we were talking about it.
Pro Football Reference = PFR below
PFR looked at thirty years of drafts and assigned numerical values based on where a player was selected and how his career played out. They then used a logarithmic formula to predict a draft pick's "approximate career value" and created a table of the results.
Sample1st round values : #1 = 73, #10 = 44, #20 = 35, #30 = 30
The values are closer to each other than Johnson's: #1 = 3000, #10 = 1300, #20 = 850, #30 = 620
With the PFR Chart #20 is approximately worth half of #1 while Johnson shows #20 to be closer to a fourth of the #1 value.
Johnson's chart is completely arbitrary while there is data behind PFRs.
There's another chart done by The Harvard Sports Analysis Collective that takes it another step and they have this to say about Johnson's chart:
...there is no statistical evidence to back up the relative values of these draft picks. There is no reason why the 156th pick is 100 times less valuable than the first overall pick. “The Chart” simply dictates how much each pick is worth. These values also have no grounding in the real worth of the players drafted at a given pick. This system is a ridiculous way to value picks because there is no reason behind the values it gives. There must be a better approach.
