Week in and week out, Boston's most important trait was its defense.
Kendrick Perkins, Kevin Garnett, and company had the interior presence that forced nearly every opponent to shoot well from the outside.
As it turned out against the Lakers, the defense on Kobe Bryant was remarkable in two of the Celtics' victories.
Kobe shot very poorly in the Game Six blowout. He was 7 of 22 in the Lakers final game. And Paul Pierce deserves all the credit in the world for guarding the best scorer in the game.
But the interior defensive presence, which reminded me of Florida rotating Noah, Richard, and Horford two years ago, was key. They handled Gasol and Odom the entire series.
Defense truly wins championships.
