John in CT and Andy in Seattle are back to recap an unbelievable first weekend in the NCAA Men's Basketball Tournament.   UMBC is the first 16 seed to upset a Number 1 seed by blowing away Virginia.  Michigan escapes toward the Sweet 16 with a near-buzzer-beater by Jordan Peele.  Marshall takes down Wichita State.  Buffalo crushes 4th seeded Arizona to eliminate the Pac 12 from the tournament entirely.  Syracuse improbably makes the Sweet 16 by taking down Michigan State on Sunday.  John, Andy, and Dave summarize the madness, then preview the Sweet 16 and Elite Eight rounds of the tourney.
