With the 2017-18 season kicking off on October 17, the NBA has now officially reached the one month point on Friday (Nov. 17). While some things have gone according to plan in the first month, there have also been many unexpected happenings.

Here are three of the biggest surprises and disappointments through one month of NBA regular season action (stats are from games through November 16).

Surprises

After starting the season 0-2, the Boston Celtics have now reeled off 14 straight wins. Their most recent win was an impressive 92-88 victory over the Golden State Warriors.

What makes their winning streak even more surprising is that they have done it without Gordon Hayward, who dislocated his ankle and fractured his tibia five minutes into the regular season. Boston has done it with a defense that ranks first in points allowed per game (94.1) and field goal defense (42.8 percent).

Second place in the East, only behind the Cetics? That would be the Detroit Pistons at 10-4, a team that finished 37-45 and 10th in the conference last season. Another early surprise for Detroit has been Andre Drummond’s 63.1 percent free throw shooting. He came into the season shooting just 38.1 percent for his five-year career.

Kristaps Porzingis was expected to become the focal point of the New York Knicks offense with Carmelo Anthony and Derrick Rose moving on.

Very few expected him to be the league’s third-leading scorer at 28.9 Points Per Game a month into the season. The 22-year-old set a new team record with 300 points in the first ten games and has scored at least 30 points in eight of his first 13 games.

Disappointments

The three-time defending Eastern Conference champion Cleveland Cavaliers are off to a slow start at 8-7.

They were able to salvage a winning record through one month by winning their last three games. LeBron James is putting up his normal numbers, but regular rotation players such as J. R. Smith, Jae Crowder, Iman Shumpert, and Dwayne Wade are all shooting 40 percent or lower.

After acquiring both Paul George and Carmelo Anthony via trade to team up with reigning MVP Russell Westbrook, the Oklahoma City Thunder were expected to be one of the main challengers to the Warriors.

The three stars struggled to integrate to begin the season, but they have at least won their last three games to even their record at 7-7. Even with three of the better scorers in the league, they are currently just 22nd in the league, averaging 103.1 points per game.

Lonzo Ball was selected second overall by the Los Angeles Lakers in the draft last June. His outspoken father has already made somewhat outlandish comments such as stating his son would become a bigger star than Kobe Bryant. While it’s not fair to judge how his career will turn out after just 15 games, to say he has struggled with his shot would be an understatement. He is 53-of-175 (30.3 percent) from the field, 17-of-74 (23.0 percent) on threes, and 12-of-24 (50 percent) from the foul line. He has shown glimpses of his abilities such as becoming the youngest player in NBA history to record a triple-double, but he has only shot 50 percent or better in one game.
