After going 56-26 and finishing second in the Eastern Conference this season, the Boston Celtics are left with some soul searching this offseason after a disappointing first round exit against the Philadelphia 76ers. 

Now, ESPN NBA Insider Brian Windhorst doesn't think the Celtics are that far from being a contender, and we agree, but that doesn't mean there aren't things to think about and questions to answer.

Let's take a look at the top four:

This season, the Celtics were very perimeter-oriented. They ranked third in the NBA in three-pointers made per game (15.5) and they were fourth in three-pointers attempted (42.1). 

Were they so three-point heavy solely because Jayson Tatum wasn't there to help balance things out? That doesn't seem quite it, because Tatum is also a volume shooter from the outside. The Celtics seemed to rely on the three-pointer because that's how they've been built.

After the playoff loss, Brad Stevens spoke about being more of a presence at the rim. Will he change course on the roster this offseason to reflect that?

An unbelievable success for the player development department, Queta played in 76 games this season, averaging 10.2 ppg and 8.4 rebounds. A 7-footer, he's certainly capable of scoring a bit and aiding in rebounding and defensive efforts.

But as Windhorst pointed out to CLNS Media, the Celtics need to figure out if he's a guy who can match up with the likes of Victor Wembanyama and Karl-Anthony Towns.

He took only eight 3-pointers this season, and while maybe that's good considering the Celtics want to be better about using the interior, would it benefit the Celtics to have more of a pick-and-pop option like they had with Al Horford?

It's been the same story for the last half-decade. Can these two continue to co-exist? To their credit, they have played well together for nine years, getting to two NBA Finals and winning one. But now that Brown has had a season acting as "the man," can he go back to his supporting role? It's something the organization has to weigh and think about.

The Celtics have the ability to add a player making just over $27 million because of the Anfernee Simons trade exception. It's presumed that the Celtics will use that by the time it expires in February, but does Boston have any qualms about simply adding that much payroll? Or do they feel the need to reduce money somewhere else, maybe in the form of Brown, Derrick White or Sam Hauser?
