At the halfway point in the NBA calendar, the Boston Celtics seem to have to steered their offense back on track after a sluggish start to the season. As things sit after game 41, the team is ninth in the NBA in offensive rating (110.8 points per 100 possessions) after holding the 27th spot 20 games into the season (104.6 points per 100 possessions). While the team doesn’t have everything figured out (their second-to-last free throw rate is a good place to start), their offense has shown a marked improvement, spearheaded not only by a stellar season from Kyrie Irving, but a historical shooting performance from … Marcus Morris.
