Michael, Scottie, Shaq, and Kobe had a lot to do with—it but they all would have lost if not for the power forward position in this offense.
Think about this if you will—each time the teams were beaten in the playoffs one portion of the triangle was not doing it's job. It has always been the power forward position.
When the Bulls lost to Shaq and Orlando, Horace Grant was on the Magic, and the Bulls had nobody "solid" at the position. The next season, they acquired a guy named Dennis Rodman and ran off three more titles, destroyed Orlando in the Eastern Finals and established the best NBA record in league history.
The Lakers went to the finals with Detroit and lost due to Karl Malone being injured. Defensive rebounds were missed, and this allowed Detroit to win that series.
This Lakers team has all the components to win the Championship—provided Andrew Bynum can provide services for longer than he did last night. Seven minutes on the court will not get it done.
Use of the Triangle offense has garnered titles for the Bulls, Lakers, and even the women's team out of Tennessee. Hall of Famers and future Hall of Famers should be really thankful for Mr. Tex Winter.
