The Boston Celtics are the No. 1 seed in the Eastern Conference, but also a team
that hasn’t won a playoff series in five years. They’ve taken clear steps
forward in their last three regular seasons under Brad Stevens, but still have a
lot to prove in the playoffs.
The Celtics have scored just 93.6 points per 100 possessions in 10 playoff games
over the last two years (getting held under a point per possession in eight of
the 10), with Isaiah Thomas shooting just 38 percent. The addition of Al Horford
has given Thomas more support this year, but the All-Star point guard will still
be the focus of opposing defenses in the playoffs, and other guys will have to
step up.
Their opponent in the first round is an eight seed, but a weird one. The Chicago
Bulls were inconsistent from game to game, capable of beating the best teams in
the league one night and losing to the worst teams the next. In fact, the Bulls
were 12-9 against the teams with the league’s eight best records, but just 13-12
against the teams with the league’s nine worst records.
You never know what you’re going to get with the Bulls and you haven’t seen
these Celtics win a playoff series yet. That makes this 1-8 series different
than most others.

Celtics notes:
Lowest NetRtg (+3.1) for a 1 seed since the 1978-79 Sonics (+2.6).
Ranked second in the league and first among playoff teams with 325.2 passes per
game.
One of five teams (and the only playoff team) that ranked in the bottom 10 in
both offensive and defensive rebounding percentage.
Took only 16.7 percent of their shots from mid-range. Only Houston (8.1 percent)
and Brooklyn (13.1 percent) took a lower percentage of their shots from between
the paint and the 3-point line.
Before the All-Star break, they ranked sixth offensively and 18th defensively.
After the All-Star break, they ranked 15th offensively and seventh defensively.
Only two teams suffered a bigger drop in OffRtg and only four had a bigger
improvement in DefRtg.
Isaiah Thomas led the league with 12.6 drives per game and 9.5 points per game
on drives.
The Celtics scored 15.7 points per 100 possessions more with Thomas on the floor
(113.6) than they did with him off the floor (99.0). That was the second biggest
on-off OffRtg differential (behind that of Stephen Curry) among 277 players who
played at least 1,000 minutes for a single team. They also allowed 8.9 points
per 100 possessions more with Thomas on the floor (108.6) than they did with him
off the floor (101.4). That was the second biggest DefRtg differential (behind
that of Andre Drummond) among that same group of 277 players.
The Celtics outscored their opponents by 349 points with Jae Crowder on the
floor. That was the third best raw plus-minus (behind those of LeBron James and
Kyle Lowry) among Eastern Conference players.
Marcus Smart’s effective field goal percentage of 42.2 percent was the worst
among 174 players who took at least 500 shots. He was one of seven players who
shot less than 30 percent on at least 200 shots from outside the paint.

Bulls notes:
Effective field goal percentage of 48.7 percent ranked last in the league. They
were a bottom-10 shooting team in the paint (24th), from mid-range (21st) and
from 3-point range (24th). But they did rank sixth in 3-point percentage (38.2
percent) after the All-Star break.
Took 28.1 percent of their shots from mid-range, the third highest rate in the
league. Only San Antonio (29.5 percent) and New York (28.6 percent) took a
higher percentage of their shots from between the paint and the 3-point line.
Ranked third defensively after the All-Star break, allowing only 102.2 points
per 100 possessions, 3.3 fewer than they allowed before the break. Only
Brooklyn, Toronto and Portland improved more defensively after the break.
Among 76 players with at least 200 pick-and-roll ball-handler possessions,
Butler had the highest free throw rate (21.2 percent).
Butler shot 59-for-62 (95 percent) on clutch free throws, the best mark among
players who attempted at least 25.
Among 164 players who took at least 250 shots before the All-Star break and 150
shots after the break, Rajon Rondo (12.8 percent) and Nikola Mirotic (12.1
percent) saw the two biggest increases in effective field goal percentage. Rondo
had an effective field goal percentage of 40.7 percent before the break and 53.5
percent after it. Mirotic: 47.1 percent and 59.2 percent.
Robin Lopez contested 1,307 shots this season, most in the league. The three
guys who contested the most shots (Lopez, Rudy Gobert, and Lopez’s brother
Brook) were the same three guys who blocked eight shots in a game this season.
