RJ Hampton's announcement that he's reclassifying and planning to play college basketball next season is a massive development in the sport. The 5-star guard is a dynamic scorer, a likely lottery pick and, at this point, projected by most to eventually enroll at the University of Memphis.

That reality has impacted the Top 25 And 1.

Since the moment the CBS Sports 2019-20 Preseason Top 25 And 1 college basketball rankings first posted, just hours after Virginia beat Texas Tech to win the national title, I've been assigning the best uncommitted Class of 2019 prospects to the schools most likely to enroll them, according to the Crystal Ball predictions at 247Sports. It's why I had Matthew Hurt on Duke's projected roster well before he committed to Duke, and Cole Anthony on North Carolina's projected roster well before he committed to UNC. Now that Hampton is officially in the Class of 2019, it's time to assign him to the school where most recruiting analysts believe he'll play. And, right now, that school is Memphis.

Combine that fact with the fact that the Crystal Ball predictions also have Memphis as the favorite to land 5-star forward Precious Achiuwa, and 4-star guard Lester Quinones, and Penny Hardaway's Tigers are now projected to have a seven-player class featuring six top-100 recruits — among them the prospects ranked No. 1 (James Wiseman), No. 7 (RJ Hampton) and No. 14 (Precious Achiuwa) in the Class of 2019. If it goes down that way, Memphis would have the nation's top-ranked recruiting class and be the lone program with three players projected to go in the top 10 of the 2020 NBA Draft, according to Jonathan Givony's latest mock draft at ESPN. So, for those reasons and more, the Tigers are now No. 5 in the Top 25 And 1 — behind Michigan State, Duke, Kentucky and Louisville.

Top 25 And 1 analysis

Biggest Movers
14 Memphis
1 Maryland
1 Michigan St. Cassius Winston's decision to return to Michigan State for his senior season was enough to keep Tom Izzo's team No. 1 in the Top 25 And 1. The Spartans are returning three of the top four scorers from a 32-win team that won the Big Ten regular-season title and Big Ten Tournament title before advancing to the Final Four. -- 20-15
2 Duke The Blue Devils are enrolling the nation's top-ranked recruiting class for the fourth consecutive year - one that's highlighted by five-star prospects Vernon Carey, Matthew Hurt and Wendell Moore. The return of Tre Jones will give Mike Krzyzewski the type of experience in the backcourt most great teams possess. -- 27-9
3 Kentucky Ashton Hagans announcing he'll return to Kentucky for his sophomore season qualified as a big development for the Wildcats. He'll be a key piece on what should be the SEC's best team. -- 23-10
4 Louisville Jordan Nwora has declared for the NBA Draft but left open the option of returning to Louisville. If he does, he'll be the leading returning scorer for a program set to enroll a top-10 recruiting class - not to mention graduate transfer Lamarr Kimble, who averaged 15.6 points per game at Saint Joseph's this season. -- 8-24
5 Memphis This ranking is based on Memphis eventually securing commitments from 5-star prospects RJ Hampton and Precious Achiuwa. If Penny Hardaway does it, and pairs them with 5-star center James Wiseman, the Tigers will arguably have the nation's most talented roster and be the obvious favorite in the American Athletic Conference. 14 22-10
6 Maryland The early loss of Bruno Fernando should mostly be offset by the return of Jalen Smith and addition of former five-star prospect Chol Marial. The Terrapins will be talented, experienced and a real threat to Michigan State at the top of the Big Ten. 1 16-17
7 N. Carolina The loss of Coby White after one season stings a little considering he didn't project as a one-and-done prospect coming out of high school. But the enrollment of five-star guard Cole Anthony should fill any hole UNC might otherwise have in the backcourt. 1 29-8
8 Kansas The Jayhawks aren't enrolling the type of recruiting class they typically enroll. But Kansas is returning enough to enter the season as the Big 12 favorite. 1 23-11
9 Gonzaga The late addition of Texas A&M graduate transfer Admon Gilder will give the Zags an experienced and reliable option at the lead guard spot. He'll combine with a top-10 recruiting class, and several nice returning pieces, to keep Gonzaga a part of the national conversation. 1 27-8
10 Virginia The Cavaliers are losing the top three scorers from their national championship team, all of whom are entering the NBA Draft early. But Tony Bennett still has enough to keep Virginia nationally relevant. 1 23-11
11 Seton Hall Kevin Willard spoke with Virginia Tech about its opening but ultimately remained at Seton Hall. He has a roster good enough to take the Pirates to the NCAA Tournament for the fifth straight year. 1 25-12
12 Villanova In a bit of a twist, Villanova will not be the favorite to win the Big East. But the Wildcats, thanks to a top-five recruiting class, should still operate near the top of the sport. 1 18-16
13 Auburn Jared Harper's decision to withdraw from school and enter the NBA Draft means Auburn is losing its top two scorers from a Final Four team. Bryce Brown, whose eligibility is exhausted, combined with Harper this season to average 31.2 points and 7.7 assists that must now be replaced. 1 27-8
14 Oregon Louis King's decision to enter and remain in the NBA Draft was a blow to Oregon. But four of the top six scorers are still expected back -- and they'll pair with a top-15 recruiting class that should make the Ducks the Pac-12 favorites. 1 24-12
15 Arizona Sean Miller, even with an NCAA cloud hovering over his program, has secured a top-five recruiting class that should return the Wildcats to the NCAA Tournament. The addition of grad-transfer Max Hazzard was a nice late development. 1 27-9
16 Michigan It appears the Wolverines are losing their top three scorers - most notably Ignas Brazdeikis. But, remember, they lost three of their top four scorers the year before and still managed to earn a No. 2 seed in the NCAA Tournament. 1 8-24
17 Iowa Tyler Cook is determined to remain in the NBA Draft, which isn't ideal for Iowa. But the Hawkeyes are still returning four of their top-five scorers - most notably Luka Garza. 1 19-15
18 Houston Houston reaching a deal on a contract extension for Kelvin Sampson was a massive development for the AAC program. The Cougars will be capable of winning back-to-back league titles. 1 32-5
19 Purdue The loss of Carsen Edwards is obviously a big deal. But Matt Painter has proven capable of running a competent program even when he loses key pieces. 1 34-5
20 VCU Every relevant piece from a VCU team that won the Atlantic 10 by two games should be back. That includes four players who averaged double-digits in points this season. -- 24-14
21 Tennessee If Grant Williams and/or Jordan Bone return, Tennessee will be significantly higher in the Top 25 And 1. But if they both remain in the NBA Draft, as expected, the Vols will have to replace the top three scorers from a team that lost in the Sweet 16. -- 27-9
22 Texas Tech The Red Raiders are expected to lose four of their top five scorers - most notably Jarrett Culver early to the NBA Draft. But, remember, they lost five of their top seven scorers from last season's team, and that didn't stop Chris Beard from getting Texas Tech to this season's national title game. -- 23-11
23 Baylor The Bears are losing Makai Mason and King McClure. But they'll get Tristan Clark back and likely make the NCAA Tournament for the sixth time in a seven-year span. -- 24-11
24 Creighton The Bluejays are returning all five starters from a team that closed the season by winning seven of their final nine games. That should be enough to help Creighton advance in the NCAA Tournament for the first time since 2014. -- 25-10
25 Ohio St. Five of the top seven scorers from a team that spent part of last season ranked are expected back - including Kaleb Wesson, who averaged 14.6 points and 6.9 rebounds as a sophomore. Those returnees, combined with a top-15 recruiting class, should have Chris Holtmann in the NCAA Tournament for the sixth straight year. -- 22-14
26 Davidson The top six scorers from a Davidson team that finished 14-4 in the Atlantic 10 are expected back - including A-10 Player of the Year Jon Axel Gudmundson. As long as Kellan Grady stays healthy, the Wildcats will be good enough to advance in the NCAA Tournament. -- 15-17
