Clemson’s rally fell short (literally) but Gonzaga and Villanova survived tough matchups to advance.  Texas also won.  After 12 games, six are a perfect 12-0 (Phantom, Batman, Krimsonguard, Baba, Buckeye Mike, AC). There isn’t a great potential for an upset in the last 4 games (only #11 VCU and #12 W.Ky are upset potentials).   Only 2 have ever gone 16-0 in the previous 14 years.  Four are floundering at 7-5.
