I always think it's funny when an AD fires a coach like JTIII because they have expectations of much better results. JTIII didn't match the performance of his father, obviously. But, in his last 11 seasons, G'town was a 2 seed 3x (2007,2008,2013) and they were a 3 seed 2x (2010 & 2012). What would they give to have results anywhere near that quality? Ewing's ineptitude to run a program has set them back 10 years.
Closest parallel I can think of off the top of my head is Boston College and Al Skinner. They beat #1 UNC on the road in 2009. Made the tournament that year. He was fired a year later... They won tournament games 4 consecutive years (2004-2007). BC hasn't even sniffed the NCAA Tournament since Skinner was fired. They are now the bottom of the barrel among the P6 schools.
