Here are five things to watch out for when the Boston Celtics and the Orlando Magic meet at 7:30 p.m. tonight at TD Garden.

Boston Back to its High-Scoring Ways

The Boston Celtics were kept under 100 points three times during its recent four-game losing streak. It was an extremely unusual stretch given that they had surpassed the century mark in 26 of its previous 28 contests.

Last night in Philadelphia, the highest scoring team in the East (106.0 points per game) snapped its losing skid with a familiar-looking offensive clinic. Boston put up 120 points and handed the 76ers a 15-point defeat. Six Celtics scored at least 15 points in the victory.

The Celtics had been experiencing a collective struggle shooting the ball, but they found their rhythm as a unit last night. Four of six Celtics who attempted at last 10 field goals shot 50 percent or better, and all five starters made at least seven shots.

“They came out focused,” C’s coach Brad Stevens said after the game. “We knew it was an important game to play well. You can’t always control the results, but you can control your input into it. Guys played with a good purpose.”

The Celtics will look to maintain that focus tonight against the Orlando Magic. Boston’s dropped at least 113 points against Orlando in each of its last two matchups.

Johnson Finding an Offensive Groove

One Celtic who’s been playing with great purpose of late is Amir Johnson. The 6-foot-9 forward has shot 74.1 percent from the floor during his last four games, including an outstanding 9-of-10 performance for a season-high 18 points last night.

The 11-year veteran has been making the most of his court time over the last four contests, putting up 10.8 points and 8.8 rebounds per game in 24.3 minutes of play.

Johnson’s recent play has caught the eyes of his teammates, particularly fellow frontcourt mate Jared Sullinger.

“He’s finishing around the rim,” said Sully, “and he’s rebounding the life outta the basketball. We need that.”

Magic Continue to Slide

Orlando entered the New Year with a 19-13 record – the fifth best mark in the Eastern Conference.

Since the turn of the calendar, however, the Magic have gone 10-27 and now sit six and a half games out of the eighth seed.

The primary reason behind Orlando’s slide is that its defense has collapsed. The Magic had surrendered the fourth-fewest PPG (98.4) in the East during November and December, but since the start of January, they have allowed the second-most PPG in the conference (107.1).

Orlando Leaning On Oladipo

There are very few positives coming out of Orlando at the moment, but Victor Oladipo’s recent play is one of them.

After a rough start to his third NBA season, the former No. 2 overall pick has seemingly turned a corner, especially during the past week.

Oladipo has averaged 28.5 points per game during his last four contests, which included a 45-point outburst during a loss to Cleveland Friday night. He has shot 58.7 percent from the field during the four-game span, including a 47.4 percent clip from beyond the arc.

The 6-4 guard has struggled against the Celtics this season, however. He scored 11 points in both games of a home-and-home series in January. The C’s have held him to a lowly 38.7 percent shooting percentage this season, including a measly 21.4 percent from 3-point range.

Celts have the Magic Touch at the Garden

The Magic have a 2-1 edge against the Celtics this season, but if history means anything, they may have a difficult time leaving Boston tonight as winners of the season series.

That’s because the Celtics have won 11 straight against Orlando on their home court. The last time the Magic won at TD Garden was a 96-92 overtime win during Game 4 of the 2010 Eastern Conference Finals.

Interestingly, the C’s have lost their last five games in Orlando. It seems as if this is one matchup where home court advantage holds true, and hopefully Boston can continue that trend tonight.
