This is an excellent article on Doc Rivers, and how he's handled the off-season of being a champion. One of the more interesting quotes, and one that I happen to agree 100% with, is the key play that kept the Celtics on their championship path:

Across the shortest summer of Rivers’ basketball life, the biggest change of becoming a championship coach had to be the way people always stopped to tell him all about the biggest shot, the biggest play, the biggest reason of the title run. They never brought up the moment that stayed with Rivers through the NBA Finals, through the summer, and all the way to training camp this week.

“After you win it,” Rivers said, “you realize how really hard it is to win a championship. You’ve got to get the right calls. You’ve got to have guys in the right spots. And sometimes, you have to get to a loose ball.”

He thinks about a jump ball. He thinks about Game 7 of the Eastern Conference semifinals, and the Cleveland Cavaliers’ 7-foot-3 center, Zydrunas Ilgauskas, reaching over Posey to tip the ball to LeBron James with a minute left and the Cavs within three points. The Celtics had a drill they always did in practice called “First to the floor,” and it was just an old-fashioned way to practice beating a man to the ball. Whatever it takes, get the loose ball. Superstars, bench players – no one sat it out. No one was exempt.

Looking back, it's pretty amazing how accurate that assessment is. A championship that came down to a simple drill that was practiced tirelessly throughout the season. As dominant as the Celtics were last season, it's a play like that that can show just how fine of a line greatness is to walk.
