What to know about recent No. 1 vs. No. 2 men’s volleyball matches

Consider it the NCAA halfway championship match.

The top two nationally ranked teams will play a two-match series this weekend in Los Angeles as USC and BYU remained No. 1 and No. 2 in the this week’s AVCA top 15 coaches poll and ASICS/Volleyball Magazine top 10 media poll.

The Trojans (9-1, 9-1 MPSF) have remained the top-ranked team since the preseason and have the fewest losses in the nation. The Cougars (13-4, 9-3 MPSF) have been No. 2 in the coaches poll for four consecutive weeks with their only conference losses coming in the first two weeks of the season against Stanford.

The frequency of the No. 1 and No. 2 teams playing each other in the regular season has significant decreased in recent years.

This weekend series is the 10th time in the last five years that the No. 1 and No. 2 nationally ranked teams will play each other in the regular season. From 2000 to 2005 the top two teams played each other in the regular season occurred almost 20 times.

If recent history tell us anything, though, do not expect both these teams to be playing against each other in the NCAA championship match in May.

Once in the last five years have No. 1 and No. 2 played each other in the regular season and then both teams reached the Final Four. UC Irvine and Pepperdine in 2007 were the only two teams to accomplish that feat, with the Waves being upset in the semifinals by IPFW and the Anteaters winning the NCAA championship.

In addition, the losers in these matches have three times ended the regular season outside of the top five nationally ranked teams.

In the second match, the Waves out-blocked the Cougars 13.5-5.5 to get the series split.
