Coaching Effect over the last 7 years

Here is the list of coaches from the article, ranked by average percent deviation from expected F/+
Some items of note/thoughts:
Brett Bielema is listed as coaching 2011 twice, with different expectations and results each time. I did not scour the data for these sorts of inconsistencies.
There is huge variation in some coaches from season to season.
There are clear cases of one hit wonders. Since Sumlin has only coached one year his ranking at number one may not be well-deserved.
While this system may not be perfect in all cases, it does seem to show a lot of the general trends that you would expect to see.
