As expected, Kyrie Irving’s first regular season with the Boston Celtics is over following a procedure on his left knee Saturday that team officials described as being "minimally invasive," that will keep him sidelined until the playoffs.

Not having Irving for the final 10 games of the regular season is certainly disappointing for Boston, but it won’t have the kind of devastating impact one might expect a team to have to endure when the leading scorer is out for a significant chunk of time.

Friday’s 105-100 win over Portland was Boston’s fifth straight game without Irving, and 12th this season.

MORE CELTICS: 

There’s no question Boston is a better team when he is in the lineup.

But when he’s not, the Celtics have continued to find ways to win games which is evident in their 8-4 record when Irving has not played.

Victories over teams like the Blazers only validates the quality depth that the Celtics players speak of when they talk about their team. 

“We know what we have,” said Boston’s Al Horford. “It is encouraging for our group. And for us it’s to make sure we keep working and understand when we commit on the defensive end, we’re a tough team to beat.”

But Horford acknowledges the challenge to be successful becomes infinity greater when key players such as Irving are out.

“We can’t dwell on the guys who are not here, the guys who are injured,” Horford said. “It’s tough, but it’s an opportunity for other guys to step up and guys have really taken advantage of that opportunity. We’re trying to move forward. It’s hard but we don’t have an option.”

 

Here are five takeaways from Boston’s 105-100 win at Portland on Friday night.

SHANE LARKIN’S PACE

The ability to not just run a team but do so in an effective, steady manner is what separated Shane Larkin from most of the guys who saw action last night. He made timely shots, kept the ball moving (he had seven assists and just one turnover) while playing at a really good tempo which was apparent as he finished with a pace of 95.97 which was tops among all Celtics players.

MONROE’S BOARD WORK

Greg Monroe could not have picked a better time to play his best basketball of the season. Against the Blazers, he came off the bench and tallied a double-double of 10 points and 10 rebounds. The 10 boards were particularly impressive with a team-best rebounding percentage of .303 and team-best usage percentage of .316 which speaks to how Boston made a point of going to Monroe early and often when he was on the floor.

EFFICIENT MARCUS MORRIS

It was another big-time scoring night for Marcus Morris who led all scorers with 30 points, easily becoming a fixture as Boston’s go-to guy now that Kyrie Irving (left knee) will miss the rest of the regular season. And like Irving, Morris is doing it in an extremely efficient manner. Against the Blazers, the 6-foot-8 forward was 9-for-13 (69.2 percent) shooting from the field with an effective field goal percentage eFG% of .885.

FOURTH QUARTER TATUM

For most of Friday’s game, Jayson Tatum was not having a good game offensively with three points through three quarters of play. But Tatum, one of the NBA’s better fourth quarter players, was once again saving his best for last. He would go on to lead the Celtics with 10 points in the fourth quarter, which was a huge factor in Boston’s comeback victory.

 

BACKUP POWER

The Celtics’ second unit looks a little different, but the production and overall impact remains strong as ever. Boston’s backups outscored their Portland brethren 26-10. But more than the points, Boston’s backups individually came up with big plays. Greg Monroe’s 10-point, 10-rebound performance stood out for obvious reasons. But the floor leadership of Shane Larkin and timely contributions from Guerschon Yabusele was also important in the win.
