Duke vs. San Diego State

The last time Mike Krzyzewski and Steve Fisher met in the NCAA tournament, they were coaching two of the most memorable teams in college basketball history for a national title in 1992.

They're facing off again more than two decades later, when Krzyzewski and the top-seeded Blue Devils (30-4) face Fisher and the eighth-seeded Aztecs (27-8) in Sunday's round of 32 in the South Regional in Charlotte, N.C.

The nearly 23-year gap will be the longest between tournament meetings for head coaches in NCAA history, according to Stats.

The '92 matchup between Duke and Fisher's Michigan team featured big names such as Christian Laettner, Bobby Hurley, Grant Hill, and the Wolverines' "Fab Five" freshmen. Duke won, 71-51, for its second straight championship.

Gonzaga vs. Iowa

Five straight years Gonzaga has exited the tournament in the round of 32. It has reached the second weekend only twice in the last 14 tournaments.

The immediate worry is the trouble Iowa (22-11) can cause with size and athleticism that matches Gonzaga's at nearly every position.

No team among the four winners in Seattle Friday was more impressive than Iowa with its 83-52 blowout of Davidson. Aaron White displayed his explosiveness as a scorer with 17 of his 26 points coming in a seven-minute span of the second half.
