Okay, things have calmed down just a bit after two of the most hectic weeks in recent college basketball history.

“Only” four of the top 10 teams fell last week (Nos. 4, 5, 7, and 8), as opposed to six last week, and seven the week before — though 12 top-25 teams did suffer a loss.

FULL RANKINGS: AP Top 25

As a result, there wasn't as much chaos in this week's AP Top 25, though it certainly wasn't stagnant. Here’s our weekly in-depth look at the latest edition of the rankings (released Feb. 13) and a glance back at the poll's 15-week history:

LAST WEEK:

35-12 -- ranked teams’ record last week, including a 15-4 mark for top-10 teams. It's definitely an improvement from last week's 10-7 record for the top 10 squads. This was the first time in three weeks that no top-10 team lost twice in the same week.

8 -- conferences that are represented in this week's Top 25. The ACC has the most teams with six, while the next closest only has three. By weighting the conferences by team rankings (No. 1 is worth 25, No. 25 is worth 1), the ACC comes out in first place, followed by the Big 12, which is tied with the Pac-12 for the most teams in the top 10 (three).

  Conference Number of teams Teams Weighted score
1 ACC 6 Louisville (8), UNC (10), Duke (12), Virginia (14), FSU (17), Notre Dame (25) 70
2 Big 12 3 Kansas (3), Baylor (4), West Virginia (9) 62
3 Pac-12 3 Arizona (5), UCLA (6), Oregon (7) 60
4 Big East 3 Villanova (2), Creighton (20), Butler (24) 32
T5 West Coast 2 Gonzaga (1), Saint Mary's (22) 29
T5 SEC 3 Kentucky (13), Florida (15), South Carolina (21) 29
7 Big Ten 3 Wisconsin (11), Purdue (16), Maryland (23) 28
8 AAC 2 Cincinnati (18), SMU (19) 15

6 -- spots, the biggest jump this week: by Duke (No. 18 in Week 14 (Feb. 6), up to No. 12 in Week 15) and SMU (No. 25 to No. 19). Last week, the Blue Devils won both of their games (both at home), taking down No. 8 UNC, then holding off unranked Clemson. SMU managed a 16-point win over Temple and a nine-point upset over No. 14 Cincinnati.

7 -- spots, the biggest drop this week: by Cincinnati (No. 11 in Week 14 down to No. 18 in Week 15). Cincinnati entered the rankings at No. 22 in Week 5. Since then, the Bearcats had been steadily climbing, not dropping in the rankings since Week 6, and not losing a game since Dec. 10. Until they went to SMU. The Mustangs pulled off the 60-51 upset at home, and the Bearcats tumbled in the Top 25.

3 -- spots, the longest upward streak: by Florida. The Gators came as close as you can to falling out of the rankings when they dropped to No. 25 in Week 12 (Jan. 23). Since then, Florida is 6-0, with a statement 88-66 win over No. 8 Kentucky on Feb. 4. The Gators have two ranked matchups approaching (against South Carolina on Feb. 21 and against Kentucky on Feb. 25). Can they keep the momentum?

3 -- spots, the longest downward streak: by Butler. In Week 12, Butler had its highest ranking of the season — No. 11. Since then, the Bulldogs are 2-3, dropping games to unranked Georgetown, No. 22 Creighton, and unranked Providence.

THIS SEASON: 

12 -- teams that have been ranked in the top 5 at some point this year. Those would be Duke (Preseason, Weeks 2, 4-8), Kentucky (Preseason, Weeks 2-4, 11, 12), Kansas (Preseason, Weeks 3-15), Villanova (Preseason-Week 15), Oregon (Preseason, Weeks 2, 14), UNC (Weeks 2-4), Indiana (Week 3), Baylor (Weeks 5-10, 12, 13, 15), UCLA (Weeks 5-11), Gonzaga (Weeks 9-15), Arizona (Weeks 13, 15) and Louisville (Week 14).

6 -- teams that have been ranked No. 1 this year. Duke (Preseason-Week 2), Kentucky (Weeks 3-4), Villanova (Weeks 5-9, 11-12), Baylor (Week 10), Gonzaga (Weeks 13-15).

40 -- teams that have been ranked at all this season.

1 -- team that has never dropped in the rankings this year: Gonzaga. The Bulldogs began the season at No. 14 and have steadily climbed to their current No. 1 spot. Gonzaga is the only unbeaten team, sitting at 26-0.

8 -- teams that were ranked in the preseason that have a net-positive ranking movement: Gonzaga (+13: started No. 14, now No. 1), Louisville (+5: started No. 13, now No. 8), West Virginia (+11: started No. 20, now No. 9), UCLA (+10: started No. 16, now No. 6),  Maryland (+2: started No. 25, now No. 23), Villanova (+2: started No. 4, now No. 2), Arizona (+5: started No. 10, now No. 5), Creighton (+2: started No. 22, now No. 20).

16 -- teams that have been ranked every week since the preseason: Villanova, Kansas, UCLA, Gonzaga, Kentucky, Creighton, West Virginia, North Carolina, Oregon, Louisville, Arizona, Virginia, Wisconsin, Duke, Purdue, and Saint Mary’s.

11 -- spots, the biggest single-week drop: by Duke. The Blue Devils fell from No. 7 to No. 18 between Week 10 (Jan. 9) and Week 11 (Jan. 16). During that span, Duke went 0-2, losing to No. 14 Louisville (78-69) and No. 9 Florida State (88-72). Oregon may have Duke beat in the anvil category. The Ducks plummeted 19 spots in two weeks, from No. 4 to No. 23 with a stop at No. 13 in between (Week 2, Nov. 14 – Week 4, Nov. 28). The Ducks were 3-2 during that stretch, falling to unranked Baylor (66-49) and unranked Georgetown (65-61).

5 -- weeks, the most one team has stayed in the same position: by three teams. Villanova stayed on top at No. 1 from Week 5 (Dec. 5) to Week 9 (Jan. 2) before falling to No. 3 for one week, then jumping back to the top spot. Kansas was No. 3 during that same span before climbing to the No. 2 ranking in Week 10 (Jan. 9). And Duke stayed at No. 5 from Week 4 (Nov. 28) to Week 8 (Dec. 26) before dropping to No. 8.
