The shuffling of schools in divisions and the addition of a division this season makes for interesting handicapping of the Division IV boys basketball tournament.

A quick review. The last four years basketball was comprised of four divisions. This year it's five. Some schools in D-III last year are D-IV this year. D-V didn't exist last year and most of those schools were in D-IV last year. There are some who competed in D-II last year now in D-IV.

You get the idea. Of the top-10 seeds in this year's D-IV  tournament, four competed in D-III last year (#1 Yuma Catholic, #5 Alchesay, #6 American Leadership and #7 Thatcher; four competed in the old D-IV (#2 Phoenix Country Day, #4 Pima, #9 Northwest Christian and #10 Arizona Lutheran) and two competed in D-II (#3 Buckeye and #8 Coronado). This bit of chemistry will be fun to watch unfold. Over the past four years seeding has been true when it comes down to the semis and finals. Only one school outside the top 7 has reached the semis in that span and the finals have pitted 1-2 twice, 1-3 once and 2-4 once.

The tournament begins Friday (Feb. 19) at neutral sites (Bradshaw Mountain HS and Prescott Valley Event Center). The round of 16 at neutral sites on Saturday (Feb. 20) followed the next week by quarterfinals Thursday (Feb. 25), semifinals Friday (Feb. 26) and the final Saturday (Feb. 27). The last three rounds are at Prescott Valley Event Center.

Here's a brief look at the top-10 seeds and how they set up for bids to the 2016 title:

No. 1 Yuma Catholic (26-1): The Shamrocks have the best record and are in the midst of a 24-game winning streak. Their only loss was to D-II Copper Canyon in a December invitational in Yuma. (Copper Canyon missed the D-II playoffs by one spot.) Yuma Catholic competed in D-III last season and was eliminated in the round of 16. This after a final four appearance in D-III the year before. The Shamrocks are led by senior guards Julian Jones and Brandon Hunter. They have two tight wins against fellow section member Buckeye (No. 3), two wins over No. 9 NWC and two triumphs over No. 10 Arizona Lutheran.

No. 2 Phoenix Country Day (22-5):  The Eagles were a quarterfinalist in D-IV last year where they lost to eventual runner-up Scottsdale Prep. They have held serve and more this season. Senior point guard Andrew Ekmark averages 24 points a game and has scoring balance behind him from forward Spencer Thompson and guards Yash Muley and Jordon Wong. PCD played two epic contests with section mate Coronado, winning in double overtime and losing by five. it's only other game against a top-10 seed was a decisive win over Arizona Lutheran, the defending champion.

No. 3 Buckeye (25-4): The Hawks benefitted this year by exiting D-II and winding up in D-IV. They were 11-13 in D-II last year and did not reach the state tournament. On much more competitive ground, Buckeye has a good shot at the title, led by senior Art Bojorquez. A pair of wins over NWC are its lone wins against top-10 tourney teams. Buckeye last won a boys title in 1990 competing in 3A. They also won in 1987 and 1988.

No. 4. Pima (25-3): The Roughriders reached the D-IV semis last year, falling to eventual champ Arizona Lutheran. They've played a healthy schedule with three games against Thatcher (two wins) and a split with No. 14 Pusch Ridge. Their only other loss was against defending D-III champ Snowflake. Famiilar names from its eight-man football championship squad in November are hoops stalwarts such as 6-foot-5 junior post Justin Kartchner and forward Johny Boren. Guards Ryan Johnson and Braven Grant lead the backcourt.

No. 5 Alchesay (25-5): The Falcons were one of those competing in D-III last year. They qualified for state, but exited in the round of 16. Three of their five losses are to D-III schools (#2 Snowflake, #6Window Rock and #12 Holbrook).and the other two to D-V  #3 San Carlos. Marquee winsin division have come against Thatcher and NWC. Senior guard Blake Lupe is the leading scorer averaging 13 points a game. The Falcons generally rely on balanced scoring behind him from Raekwon Cosay, Olajuwon Quintero and Lamar Ray.

No. 6 American Leadership Academy (25-5): The Patriots had a good season last year (18-10), but didn;t qualify for state competing in D-III. They have a good inside-outside attack led by 6-6 forward Donovan Hanna (15 points a game) and scorer in the backcourt in senior Myles Thompson (12 ppg). D-IV losses are to Coronado and Chandler Prep. American Leasdership has its share of wins against tournament top-15 seeds including Thatcher, AZ Lutheran, Florence and Pusch Ridge.

No. 7 Thatcher (20-8): The Eagles hung tough in D-III last year advancing to the semifinals before narrowly falling to Combs (46-44). Thatcher is usually in the title chase regardless of division. Half of its losses in 2016 are to D-III teams and all of those were by double digits. Against top-10 D-IV seeds the Eagles are 1-4 (two losses to Pima, one each to American Leadership and Arizona Lutheran). Several players from last year's deep run are back -- post Jared Jorgensen, forward Jace Smith an guards Chase Layton and Carson Goodman.

No. 8 Coronado (17-9): Like Buckeye, the Dons have made vast improvement dropping from D-II to D-IV. Coronado was 6-20 last season. They've lost most of their games to to D-I, II and III opponents. They enter the tournament with momentum from a huge rally in the final period that alowed them to defeat No. 2 Phoenix Country Day and earn a split of tight games with PCD. Coronado also split close games with #12 Chandler Prep. The Dons are led by senior guards Braden Pixley and Aaron Rhymes.

No. 9 Northwest Christian (15-10): The Crusaders competed in D-IV last year, but didn't qualify for the tournament posting a 9-17 record. This year a reversal. NWC has five losses to D-II and D-III schools. The other five are to top-5 D-IV tournament seeds -- #1 YC, #3 Buckeye (2), #4 Pima and #5 Alchesay. They have a handful of wins over other teams in the D-IV field -- namely #10 Arizona Lutheran (2), and #11 Lee Williams. The Crusaders missed a first-round bye by one slot and open with #24 St. Johns.

No. 10 Arizona Lutheran (15-11): The Coyotes lost a big chunk of their D-IV title team from last year to graduation so they've had to retool a bit. Seven of their 11 losses this season are to top-10 D-IV seeds -- #1 YC (2), #2 PCD, #3 Buckeye #6 American Leadership and #9 NWC (2). ALA has work to do if it wants to reach the D-IV final for the fifth straight year. It's won the last two and been runner-up the two prior to that. Forwards Gabe Galvan, Aaron Rosenbaum and guard Cameron Haag were intergral pieces to the title run a year ago. Senior guards Tremell Carson and Timmy Lastrange have stepped up this year to help. ALA opens the tournament taking on Morenci. A win there earns it a shot vs. #7 Thatcher.
