The Boston Celtics will take the floor for the first time since their disappointing first-round loss against the Philadelphia 76ers in the Eastern Conference playoffs on Friday night.

The game against the Toronto Raptors on Friday (9 p.m. ET) will kick off the C's run in the Las Vegas Summer League.

Boston will play four games as part of Summer League, with a potential semifinal playoff game to come on July 18 and the Summer League Finals to come on the 19th.

While regulars like Jayson Tatum and Payton Pritchard won't play, there are several things worth watching for in the Summer League, so let's break down three big ones.

Gonzalez played in 74 games this past season, averaging four points a game and serving as a valuable piece when Jayson Tatum was out with injury. Tatum only played 16 games as a result of recovery from his torn Achilles.

As a result of his NBA experience, Gonzalez figures to be the leader of the Summer League Celtics. How that manifests itself will be important to see. Is he able to score easier? Is he a leader on the floor? A playmaker? 

He was all of those things with Spain at the recent FIBA qualifiers. Celtics fans should be looking for more of the same in this run.

Summer League isn't indicative, necessarily, of how the Celtics will play will play in 2026-27, but it is a curiosity.

After being one of the most three-point dependent teams in the NBA last season, Brad Stevens has talked about getting more balanced. Will we see that here, especially with rookie Chris Cenac Jr. helping anchor the interior? Or will we see a team that runs a lot and fires from the perimeter?

Head coach Amile Jefferson, who is a Celtics' staffer, should have some unique say in the style of play.

Speaking of Cenac, this will be the first look for Celtics fans at the first-round pick from Houston, as well as Dillon Mitchell, the team's second-round pick from St. John's.

A 6-foot-11 center from New Orleans, Cenac played for Kelvin Sampson with the Cougars, seeing time in 37 games. He started 36 of those contests, playing 25 minutes a game and averaging 9.5 points and 7.9 rebounds. Long and athletic, he also averaged 0.5 blocks per night and he also had 0.8 steals.

Mitchell began his career at Texas, starting 38 games as a true freshman and averaging 4.3 ppg before scoring 9.6 as a sophomore. He transferred to Cincinnati as a junior, scoring 9.9 ppg before landing at St. John's for his senior year. He averaged 8.3 ppg and seven rebounds while also dishing three assists per game. He's listed at 6-foot-8.
