Pierce will be relied upon to score consistently next year.
Though everyone expected the Celtics' Big Three to be an unstoppable force of offensive firepower, that really wasn't the case.
In fact, in the Big Three era, the Celtics were never an elite offensive team.
The C's, who hang their hat on defense, haven't been a top-10 scoring team since they acquired KG and Allen. They bottomed out last year on offense, scoring only a paltry 91.8 points per game, good for 26th in the league.
Part of their issue has been rebounding on the offensive glass, which was historically bad last season, when they were dead last in offensive rebounding with 509, 131 fewer than the second-to-last-ranked Warriors.
While that's part of Doc Rivers' scheme (he emphasizes transition defense over aggressive offensive rebounding), it has led to very few possessions per game, and thus lower scoring.
They also wasted too many possessions last season running sets for Ray Allen. Allen can no longer create his own shot (something he was never great at) and instead requires multiple screens to free him for a look at the basket.
Thus, the Celtics would run plays where Rondo would hold the ball at the top of the key, waiting for Allen to fight through picks to get open. If it didn't work out, Rondo would simply have to ad-lib with only a few seconds on the shot clock.
While the C's would have loved to have had Allen back off the bench (he departed for a bigger role with the rival Miami Heat this offseason), it may just be a blessing in disguise that he departed.
The team is now Rondo's to run, and it's his responsibility to get Pierce and KG the looks they need to score. KG thrives facing the basket, as his elbow jumper is one of the silkiest in the league.
Pierce needs the ball in his hands more often, and while isolation plays aren't necessarily the answer, with Allen gone the "Truth" will need to be even more aggressive on offense.
Thankfully for the C's, they've finally got a bench that can score when the starters are out.
But even with their depth and talent, Boston will need its two future Hall of Famers playing at their best if they hope to make a deep playoff run next season.
