Husky, here is SD's body of work at BC:
2010-11: Overall: 21-13 (incl. 1-1 NIT) ACC: 10-8 (With Al Skinner's players)
2011-12: Overall: 9-12. ACC: 4-13.
2012-13: Overall: 16-17. ACC 8-12.
2013-14: Overall 8-24. ACC 4-13.
Other than the first year with Al Skinner's players, this is not a good record. Add in the many embarrassing losses (Bryant, College of Charleston, BU, etc), not sure how anyone can argue that he deserved another year.
It just didn't work out. The record is pretty telling. What other schools would tolerate that kind of performance?
