1. Loyola (4-0) Key players: PG Parker Jackson-Cartwright, SG Justin Childress, SG Jacob Hazzard, SF Julian Harrell (Penn)
Last season: The Cubs went 25-6 and won the CIF-Southern Section Div. I-A championship before losing by two to eventual state champion Mater Dei in regionals.
Why they're here: Jackson-Cartwright, only a sophomore, is already considered the top point guard in the state. Mix in the shooting of Childress and Hazzard -- as well as the versatility of Harrell -- and the Cubs have a lineup that few can match.
2. Long Beach Poly (3-1) Key players: SF Roschon Prince, PF Jordan Bell, PG Chris Croom, SG Reuben Strickland
Last season: The Jackrabbits posted a 30-2 record and captured the Division 1AA title in Anaheim before losing to eventual state champion Mater Dei in regionals.
Why they're here: Poly coach Sharrief Metoyer lost his top two to graduation -- state player of the year Ryan Anderson (Boston College) and Alexis Moore (USC) -- but there's more than enough talent left. Prince and Bell might be the best one-two combination in the county.
3. La Verne Lutheran (4-0) Key players: PF Grant Jerrett (Arizona), SG Eric Cooper Jr. (Arizona), SF McKay Anderson, SG Cameron Osorno
Last season: The Trojans overcame off-the-court adversity, finishing with a 25-5 mark and a second consecutive state championship.
Why they're here: Jerrett, a long and lean power forward, is arguably the top prospect on the West Coast. Coach Eric Cooper Sr. returns nine letter-winners from last year's team, including son Eric Cooper Jr., a sharp-shooting junior who makes teams pay for double-teaming Jerrett down low.
4. St. John Bosco (4-0) Key players: SG Isaac Hamilton, PF Anthony January (UTEP), SF Darryl Matthews, SG Daniel Hamilton
Last season: The Braves finished 21-9 and were eliminated in the quarterfinals of the CIF-SS Division 4AA playoffs.
Why they're here: New coach Derrick Taylor, who built Woodland Hills Taft into a City Section power, has the Braves thinking about the Trinity League crown. Getting past defending state champion Mater Dei won't be easy, but Bosco has Isaac Hamilton, a transfer from Crenshaw who is one of the nation's top juniors.
5. Price (3-1) Key players: PF Skylar Spencer (San Diego State), PG Chance Murray, SG Chris Sandifer
Last season: The high-flying Knights went 24-8 and fell just short against La Caņada in the CIF-SS Division 3AA championship game.
Why they're here: Yes, Price lost guard Askia Booker (Colorado) and ultra athletic forward Norvel Pelle to graduation but don't dismiss coach Michael Lynch's bunch. Spencer is another high-soaring scorer who's lethal in fast break opportunities, and Murray, a junior, already has a scholarship offer from UCLA.
6. Compton (3-1) Key players: SF Victor Robbins, SG Isaiah Bailey, PF Pruitt Roman, PG Lorenzo Murphy, PF Chris Lewis
Last season: The Tarbabes, by all accounts, underachieved. They finished 21-15 and were bounced in the first round of the state playoffs.
Why they're here: The Tarbabes could make a run at the Moore League title. Robbins, a slasher who makes good decisions with the ball, might be the best player on the floor on any given night and Bailey, only a sophomore, is an up-and-coming guard prospect who could be the X-factor. Roman, meanwhile, is tough around the basket.
7. Gardena Serra (0-0) Key players: PF Daddy Ugbede, SF Dakarai Tucker, SG Kejon Mack, C Emmanuel Ndumanya
Last season: The Cavaliers went 14-11 after forfeiting 13 wins for using an ineligible player. They were left out of the playoffs.
Why they're here: The defending Del Rey League champions are deep and as athletic as any team out there. Ugbede and Ndumanya are works in progress but have shown tremendous upside (Ndumanya shattered a glass backboard with a dunk in the fall). Tucker, Mack and junior guard Marc Rodgers are the three returning starters.
8. Windward (1-1) Key players: SF Nick Stover (Loyola Marymount), PG Jordan Wilson, PF Matthew Walker, PF Mason Shepard, SG Luke Silverman-Lloyd
Last season: The Wildcats won a state championship for the second time in three years and finished with a 27-8 record.
Why they're here: Stover, the younger brother of UCLA reserve Anthony Stover, is a crafty wing player who thrives when attacking the basket. Coach Miguel Villegas must find ways to make up for the loss of standout Wesley Saunders (Harvard).
9. Fairfax (4-1) Key players: SF Taj Adams (Loyola Marymount), SF Brendyn Taylor, PG Landon Drew, SG Amir McCormick
Last season: The Lions did not meet lofty preseason expectations, going 17-10 and losing to eventual runner-up Westchester in the second round of the City Section playoffs.
Why they're here: Fairfax is a legitimate contender in Division I of the City Section. Coach Harvey Kitani has the depth and experience to make noise. Drew, the son of Atlanta Hawks coach head coach Larry Drew, was an All-City first-team selection last year.
10. Damien (1-0) Key players: PF Chris Reyes (St. Mary's), SG Jeremy Hemsley, PG Clayton White, SG Jared Dizon
Last season: The Spartans went 26-4 and reached the CIF-SS Division 3A semifinals, where they fell to eventual champion Harvard-Westlake by three.
Why they're here: Reyes, a 6-foot-7 forward, might be the best senior prospect you've never heard of. Coach Matt Dunn has the luxury of using him down low, but Reyes can also consistently knock down the mid-range jumper. Hemsley is one of the area's better freshmen.
