Interesting to look at the recruiting gap across time of the average team class ranking within the conference - I only used numbers from scout as this was the easiest to pull quickly by conference. Nebraska, Missouri and A&M were added as they joined the conference.
Notable time frames:
2004 and 2005 was the smallest gap - this would have translated to Junior and Seniors on the field in 2006 and 2007. And as you can see 2009 to 2012 were not so great and that would translate to Juniors and Seniors on the field in 2011 to 2014...The last 3 years including the upcoming 2015 have shown some improvement.
Hopefully that tweet embedded correctly...
