The "dream round" of the Oahu Interscholastic Association Division I football tournament opens Friday with three games and Saturday with one.

It's the "dream round" because since the advent of the 12-team format in 2011, no third through sixth seed has advanced to the semifinals.

In fact, it has been pretty much the top seeds advancing to the title game. Only once a second seed (Kahuku in 2011) has made the title game. The rest were battles of the top seeds.

In opening-round games, the sixth seed has won once (Aiea 13, Kailua 12 in 2011). The fifth seed has won twice (see list below). 

The only time a semifinal featured teams from the same division was last year, when Blue 1 Mililani played Blue 3 Campbell, the only non-bye team to reach the semifinals.

Who will break the trend?

Friday

Castle (Red 5) at Kapolei (Blue 4)

Series tied at 1; only meetings were in postseason. Kapolei won last year's first round, 34-0. 

Moanalua (Blue 5) at Leilehua (Red 4)

Leilehua leads series 24-0. Last three meetings (2011 to 2013) were in the OIA tournament.

Waipahu (Red 6) at Kailua (Blue 3)

Waipahu leads series 16-10-4. Teams haven't met since 2000. They were scheduled to play in preseason last year, but the game was canceled because of weather system Isele.

Saturday

Campbell (Blue 6) at Kaiser (Red 3)

Campbell leads series 6-4.
