Below is a look at retention rates and numbers around the Big 12 for players signed in 2014 and 2015, Kingsbury's first two full recruiting classes as he joined Tech in December of the 2013 cycle.

The attrition rate is alarming to say the least. For example Texas, who is down and recently went through a coaching change, has more guys still on the roster from the 2015 class (21) than Tech has from the 2014 and 2015 classes combined (17).

My method is simple; I am cross referencing each team's signing class with their spring roster. If a guy on the commit list isn't on the roster a simple search usually explains why in a minute or so.

Here's a list of percentages representing how much each program has retained from their respective 2014 and 2015 classes:

UT: 73%

TCU: 71%

BU: 68%

WVU: 57%

OKST: 57%

K-State: 57%

OU: 56%

KU: 52%

ISU: 49%

Tech: 37%
