Kiper Vs. McShay Vs. Mayock Death Match: Who's The Best Mock Drafter?
With the NFL Draft pundits rolling out their final mock drafts this week, which one should you pay the most attention to?
We have graded the Round 1 mock drafts of Mel Kiper (ESPN), Todd McShay (ESPN), and Mike Mayock (NFL.com) for each of the past six years (2008-2013). Here are the results.
Let's start with our simple variability measure, which is based on the difference between when each player was projected to be picked and when he was actually picked. A lower variability score is better:
| Variability | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | Average |
|---|---|---|---|---|---|---|---|
| Mayock | 7.3 | 9.6 | 9.9 | 9.3 | 7.9 | 10.7 | 9.1 |
| Kiper | 10.1 | 8.8 | 10.4 | 7.7 | 8.5 | 11.7 | 9.6 |
| McShay | 10.7 | 8.7 | 8.8 | 6.8 | 7.0 | 21.5 | 10.6 |
Mike Mayock has posted the best average. Todd McShay had a great run from 2009-12 but stumbled badly last year (as did all of the pundits, but McShay did even worse).
Here are all the individual major Hits and Misses from the pundits for each of the years:
The variability metric can be significantly impacted by "outliers" such as McShay picking Ryan Nassib to go #7 last year (he went #110), so we have calculated a few alternative metrics, including Median Error and Hit Rate.
Median Error (lower = better)
| Median Error | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | Average |
|---|---|---|---|---|---|---|---|
| Mayock | 2.0 | 4.0 | 3.0 | 3.0 | 3.5 | 3.5 | 3.2 |
| Kiper | 3.0 | 3.5 | 3.0 | 4.0 | 3.0 | 3.5 | 3.4 |
| McShay | 4.0 | 4.0 | 3.0 | 3.5 | 3.0 | 5.0 | 3.8 |
Hit Rate (higher = better): pure percentage of how many picks were correct
| Hit Rate | 2008 | 2009 | 2010 | 2011 | 2012 | 2013 | Average |
|---|---|---|---|---|---|---|---|
| Mayock | 35% | 28% | 22% | 28% | 19% | 28% | 27% |
| Kiper | 29% | 25% | 31% | 28% | 22% | 25% | 27% |
| McShay | 16% | 25% | 34% | 25% | 16% | 22% | 23% |
