It has been awesome for certain, easily the greatest event in sport.
But for overall drama, it was in the early 80's when in the opening round, 4 or 5 games had incredible finishes, all finishing within 10 minutes of each other, it seemed.
US Reed made a mid-court shot to win for Arkansas, and Danny Ainge went coast-to-coast on a layup to win for BYU, and memory escapes me as for the specific examples, but there were numerous buzzer beaters and heartbreakers, sort of putting the tourney on the map.
The regional final games in 2005 are hard to top, though the year Christian Laettner had two buzzer beaters in OT thriller v UK was one of many classics that year.
I just hope the high level of quality games can continue for the last three games, as last year produced two nail-biters in the semis, leading to anticlimactic rout in the Final.
