Trailing 0-2, the Bulls made a strong statement in Game 3. Big games by the rest of the team in the third quarter, gave Red Bull a commanding 17-point cushion. Despite a fourth-quarter rally by Purefoods, the Bulls held on to cut the margin to just one game, going into Game 4.
Purefoods started hot from the get go with key games from newly crowned MVP James Yap and Most Improved Player Marc Pingris. The Giants led by as many as 34 points and the Bulls never looked back as Purefoods needs one more win to clinch their first crown since 2002.
Purefoods was on the verge to win the title with a 15-point third quarter lead behind the strong shooting of James Yap. But Red Bull fought back in the fourth quarter as Enrico Villanueva and the Bulls slowly mounted a comeback to steal the game from the Chunkee Giants extending the series to a sixth game.
Purefoods and Red Bull had a see-saw battle, with neither trailing by more than ten points. By the halfway mark of the fourth quarter, Red Bull committed a barage of fouls that led to freethrows for Purefoods, which a majority were converted. Missed freethrows by Barako Junthy Valenzuela sealed defeat for the Barakos.
Talk N' Text failed to enter the quarterfinals for the first time since the 1998 All-Filipino Cup, when the then-Mobiline Phone Pals failed to enter the semifinals of the said tournament.
Barangay Ginebra failed to enter the semifinals for the first since the 2003 Reinforced Conference.
Coca-Cola and Alaska met for the first time since Alaska won the 2003 Invitational tournament over the Tigers.
Alaska's defeat in the semifinals was the third time that the Aces fail to beat Purefoods after leading a series 2-0. In 1990, Alaska lost to Purefoods, 3-2 in the Third Conference Finals after they won the first two games of the series. In 2002, the Aces lost to the then-TJ Hotdogs in seven games after taking a 2-0 series lead. In the semifinals, they had a 2-0 and 3-1 series leads.
San Miguel has not won a seventh game since 1992, since defeating Purefoods for the Third Conference crown. Since then, the Beermen lost to Alaska in the 1995 Governors Cup Finals and the 1998 All-Filipino Cup, to Coca-Cola in the 2003 Reinforced Conference Finals and to Red Bull in the 2006 Philippine Cup semifinals.
Red Bull has won all Game 7s they have played since joining the league in 2000. Red Bull defeated Talk N' Text for the 2002 Commissioners Cup trophy. In the 2006 Fiesta Conference semifinals, the Bulls beat Barangay Ginebra and in the 2006 Philippine Cup Playoffs semis, they won over San Miguel.
It was Purefoods' 11th finals appearance in the All-Filipino Conference, now called as the Philippine Cup since the 2004-2005 event. They have won four All-Filipino titles in history with the 1997 edition as their last.
A win by Red Bull in the finals would sweep all the titles available in the 2005-2006 PBA season. It would be the first since Alaska won the PBA grand slam in 1996. However, the term grand slam, provided a Bulls win in the Philippine Cup, is disputed as of the moment.
The Red Bull-Purefoods finals duel was the first back-to-back conference finals matchup since 1998, when Mobiline Phone Pals and the Formula Shell Zoom Masters met in the special 1998 PBA Centennial Cup and the 1998 PBA Governors Cup. The Phone Pals won 67-66 in the one game Centennial final, while the Zoom Masters defeated Mobiline in seven full games to win the Governor's Cup. With the Centennial Cup being classified as a special tournament, the last back-to-back full conference Finals match-ups was between Alaska and San Miguel in the same 1998 season, at the All-Filipino and Commissioner's Cups.
