Starting with Stanley Johnson, the Santa Ana (Calif.) Mater Dei small forward ended an extremely successful high school career ranked 3rd overall, moving up from his previous ranking of 7th. The Arizona signee led Mater Dei to a city and state title, showing improved ball skills, passing and shooting ability during an undefeated senior season.
Making another major jump forward from UCLA signee Thomas Welsh, going from 45th to 17th. The Los Angeles Loyola center has made extremely impressive strides over the last couple of years and to go along with elite hands, he has become more mobile, added a better face up game and improved his skill level and footwork around the basket.
Jumping from 50th to 32nd is another Loyola player in Parker Jackson-Cartwright, headed to Arizona. Over the course of his senior season, Jackson-Cartwright proved much more durable, grew, got stronger, quicker and further displayed an elite basketball IQ.
Going from unranked to 40th is Los Angeles Westchester shooting guard Elijah Stewart, who previously signed with LMU. Stewart is one of the national surprises of the season, coming out of seemingly nowhere to prove himself as one of the top shooters and scorers in the country.
Debuting into Scout.com's rankings at 61st overall is Long Beach Marquetti small forward Malik Marquetti. An extremely versatile wing signed with USC, Marquetti is a terrific rebounder, passer, plays very hard, can slash, hit the open shot and defend multiple spots.
Also entering our rankings for the first time at 67th is Sacramento Capital Christian face up four D.J. Wilson. Over the course of his senior year, the Michigan signee grew to at least 6-foot-8, started to fill out his long frame, became more athletic, played harder, rebounded well, blocked shots and improved his scoring ability.
Phoenix Sunnyslope center Michael Humphrey, signed with Stanford, ends up ranked 71st, up from 80th. Humphrey has a good frame for a young post with an elite motor. His skill level and footwork is still coming around, but he's made strides in those areas since emerging on the national scene in June of 2013 and has become a much better shooter.
Coming in at 73rd is Denver East shooting guard and Creighton signee Ronnie Harrell, who was previously unranked. Harrell already had nice size at 6-foot-6 but is starting to get stronger, becoming a more consistent shooter, improving his ball skills and showing better athleticism.
Finally, another prospect debuting into the rankings as a senior, is Mission Viejo (Calif.) small forward Chandler Hutchison. The Boise State signee was already a big time defender who can guard multiple positions, but he's gotten stronger and really improved as a scorer as well.
