I mean, here's his postseason performance at Arizona (he also has an E8 and a S16 from Xavier, as a 3 and a 4 respectively):
2010 None
2011 E8 (5 seed)
2012 NIT
2013 S16 (6 seed)
2014 E8 (1 seed)
2015 E8 (2 seed)
2016 R1 (6 seed)
That's nothing to laugh at. He over-performed twice, met seed once, under-performed once, and the 1 seed in the E8 is about normal. Twice the Elite 8 Game came down to the last second (wide open 3 vs. us at the buzzer, controversial travel vs. Wisconsin in 2014). If you look at Calhoun, even if you start it at 1989:
1989 NIT
1990 E8 (1 seed)
1991 S16 (11 seed)
1992 R2 (9 seed)
1993 NIT
1994 S16 (2 seed)
1995 E8 (2 seed)
1996 S16 (1 seed)
1997 NIT
1998 E8 (2 seed)
You'd probably have been among those who said Calhoun couldn't win the big one.
