NFL Draft Slotting

By Tangotiger, 02:22 PM

Phil Birnbaum points to an article here with a cool chart that assigns a value to each draft slot.  If you work it out, it basically becomes a logarithmic function that looks like this:


value of 1st pick is: EXP(7.5) = 1939
value of 2nd pick is: EXP(7.5*.995) = 1867
value of 3rd pick is: EXP(7.5*.995^2)=1798

Or, in short: EXP(7.5*(.995^(pick-1))), where EXP() is the Excel function, which is a constant close to 2.718.  The ln of e = 1.

It works well except for the first 3 or 4 picks, as the NFL gives a premium over and above this quick function.  Whether the NFL is right, or the quick function is a better tool, is subject for someone else to research.  In any case, I prefer quick functions to carrying around a table with 224 entries.

Rany also had a wonderful series of articles last year on Baseball Prospectus.  Philly over at Sons of Sam Horn also had a sensational set of articles.

What I would be interested in is a study correlating draft players bonuses with their production. Because I think what gets lost in the whole discussion of how much a player is worth is the cost of signing him originally. In fact if the draft market is efficient once you combine bonuses and adjust for real and salary inflation you should get the same dollars per marginal win as you get from free agents.

I definitely agree that bonuses (and recruiting and player development costs) need to be added in to a player’s expenses, not just salary.

While we like to believe that the minimum MLB payroll would be 10 million$ a year, we can’t also forget the 30 million$ (or whatever it is) in bonuses, recruiting, and minor league costs.  So, you really need 40 million$ to field a team every year of 18-22 yr olds (which may include some real quality players).  Maybe such a team would have a .400 record.

A team that existed without a minor league or drafting system at all (all players made up of discards of other teams, basically guys over 27) would cost 10-15 million$ a year, and would play at .300.

An average MLB team probably has 110 million$ in salary + bonus + minor league + recruiting.

So, to go from .300 to .400 costs about 30 million$.  To go from .400 to .500 costs about 70 million$.

That makes it a bit under 2 million a year for the young player wins, and a bit over 4 million a year for the old player wins.

Feel free to make up your own numbers (I did!).  I think you’ll still find that the young player costs are still much less than the old player costs.
