It wasn’t that long ago that the Atlantic Division was the worst in the NBA. But this year, the Atlantic was one of two divisions with four playoff teams. And now, it’s the only division with three teams in the conference semifinals.

This series pits the two teams that finished atop the division against each other. The Toronto Raptors are in the playoffs for the sixth straight season and this may be the best team in franchise history. The same can’t be said about a historic franchise like the Philadelphia 76ers, but the Sixers have come a long way from when they went 10-72 just three seasons ago.

Both teams took care of business in the first round after dropping Game 1 at home. And both teams have starting lineups that have been absolutely dominant.

The only other time these two franchises met in the playoffs was in the conference semifinals in 2001, when Vince Carter missed the potential game-winning shot in Game 7 and the Sixers went on to reach The Finals.

Matchup notes:

1. The Sixers have lost 13 straight games in Toronto.
2. All four games took place before the Raptors traded for Marc Gasol and the Sixers traded for Tobias Harris. The first meeting took place before Philadelphia traded for Jimmy Butler.
3. The Raptors were 3-0 against the Sixers with Kawhi Leonard, who is 13-0 in his career against Philadelphia and missed the Dec. 22 game. Serge Ibaka also missed that game and Fred VanVleet missed the first meeting for Toronto. J.J. Redick missed the fourth meeting for the Sixers.
4. Toronto scored 116.1 points per 100 possessions over their three wins and just 91.8 in their one loss.
5. In the Dec. 22 meeting, the teams combined for 61 fast break points. The Sixers’ 33 were the most they registered all season. The Raptors had 27 or 28 in each of the first three meetings, three of the seven highest fast-break-point totals against the Sixers.
6. Over the four games, the Sixers had 20 more turnovers than the Raptors (75-55). Philly had a turnover rate of 20 per 100 possessions in their three losses and just 11.8 per 100 in their one win. Ben Simmons’ 25 turnovers were 10 more than he had against any other opponent this season.
7. Leonard was the primary defender on Simmons and in the three games he played, Leonard had 12 steals, four more than any other player had vs. Philadelphia in the regular season.
8. Gasol did play two games against the Sixers with the Memphis Grizzlies, who had success defensively on the possessions in which Gasol defended Embiid. The 8-for-28 (29 percent) that Embiid shot against Memphis was the worst he shot against any opponent that he faced more than once this season.
9. Harris played two games vs. Toronto when he was with the Clippers. The 9-for-28 (32 percent) he shot over the two games was his second worst mark vs. any opponent this season. His primary defenders were Pascal Siakam (33 possessions) and Danny Green (31).
10. Siakam was the primary defender on Butler, who shot 12-for-19 (and more often than usual) on those possessions.
11. The Sixers were one of two teams to shoot better than 70 percent in the restricted area against the Raptors. Butler, Embiid and Simmons combined to shoot 57-for-77 (74 percent) in the restricted area and 30-for-88 (34 percent) outside it.
12. The 38 free throws the Sixers made (on 41 attempts) in the Feb. 5 meeting were tied for the fourth most for any team in any game this season. (The Sixers also had the three highest totals.)
13. Green had an effective field goal percentage of just 37.5 percent against Philadelphia, his worst mark against any Eastern Conference opponent.
14. The Raptors’ worst plus-minus against the Sixers belonged to Greg Monroe, who was a minus-29 in his 45 minutes in the season series … and now plays for Philadelphia.
