Thanks for the submission. Great article. The conclusion that coach Golden's defense has been pretty effective against the run is a little misleading.
Under coach Golden, we have made far fewer big plays defensively and have given up big plays defensively at about the same rate as under coach Shannon.
% of running plays equal to or less than 0:
Shannon
2008 25%
2009 25%
2010 24%
Golden
2011 18%
2012 14%
2013 15%
2014 17%
% of running plays of 11 yds. or more
Shannon
2008 12%
2009 12%
2010 12%
Golden

2012 14%
2013 12%
2014 10%
So, the read and react approach is supposed to make it more difficult for an opponent to achieve big running plays and to accomplish this, you are willing to make fewer big plays on defense. Well, we certainly make fewer big plays on defense, but we haven't been rewarded by our opponents making fewer big plays.
