The Chicago Bulls are 1-3 after falling to the Boston Celtics on Monday night, 134-99. However, the gauntlet is just getting started for Tiago Splitter's team.

Starting with Monday's game in Boston, the Bulls play 10 consecutive games against teams that reached the playoffs last season. That includes two games against the Celtics, Knicks and 76ers, as well as one game apiece against the Spurs, Hawks, Timberwolves and Cavaliers.

Although Chicago managed to keep the game close for most of the first half, Boston's ability to explode and pull away from the Bulls like it did shows just how vast the gap between the two teams is. That could be a bad omen heading into the Bulls' brutal stretch.

Here are the four biggest takeaways from the Bulls' loss to the Celtics:

The Bulls entered Monday's game as the NBA's worst three-point shooting team, making just 22.6% of their shots through three games. That trend continued early against Boston.

Splitter's squad managed to find open looks, but just couldn't knock them down. In the first quarter, the Bulls got a whopping 17 three-point shot attempts up, but found the bottom of the net on just four of them.

Chicago followed up its brutal start with a more balanced second quarter, in which it went 4-of-8 from downtown. That short stint of success fell off after halftime, though, as the Bulls shot 4-of-19 on threes in the second half. Norman Powell was responsible for four of the Bulls' 12 three-point makes.

After dunking everything in sight during Saturday's loss to the Wizards, Wilson displayed his skill and finesse against the Celtics. He got on the board with a pull-up jumper, then drove through contact from Paul George for a crafty finish. In the second quarter, the 20-year-old navigated traffic with a euro-step before converting another and-one. That was in addition to his athleticism-driven plays, such as two first-quarter blocks against George and Jayson Tatum.

Although Wilson's stats didn't pop off the page as they did in his 30-point, 14-rebound performance on Saturday — he finished with 17 points, five rebounds, three assists, two blocks and a steal on 7-of-15 shooting — he also played great defense against Tatum. While guarded by the No. 4 overall pick, the perennial All-Star made just one of his five shots. Comparatively, Tatum shot 6-of-12 while guarded by anyone else.

Halfway through the third quarter, the Celtics led the Bulls, 76-66. Then came the rain.

Boston ended the period on a 29-9 run, most of which came from seven three-pointers. Celtics guard Payton Pritchard (19 points) nearly outscored the Bulls (21 points) by himself in the third as the C's pulled away from Chicago.

For all intents and purposes, Boston's eruption from deep shouldn't come as a major indictment for the Bulls' three-point defense; the Celtics' system does this to everyone. With Splitter's desire to aggressively crash the glass, Boston was bound to capitalize by spraying a few offensive rebounds back out to open shooters.

Chicago has had to make do with Nic Claxton out with a hamstring strain to start the year. Jalen Smith — a true power forward — has started at the center spot, while Splitter has rotated between Zach Collins and a combination of Leonard Miller and Noa Essengue as a small-ball '5' off the bench.

Boston exploited this, as seven-footers Mitchell Robinson and Neemias Queta finished off lobs and post-entry passes all night long. Tatum caused problems as well and showed no signs of rust from his previously torn Achilles. In total, the Celtics outscored the Bulls in the paint, 46-30.
