The 2026-27 season is the most consequential in UC Davis basketball history — and it hasn't tipped off yet. After 19 seasons in the Big West, the Aggies are moving to the Mountain West Conference, a step up in competition, exposure, and ambition that redefines what the program can be. Head coach Jim Les, entering his 16th season, will lead UC Davis into its new league with 383 career wins — 229 of them as an Aggie — tied for 50th among all active Division I head coaches. The move is a validation of everything Les has built in Davis. Now comes the harder part: winning in the new neighborhood.
Les has been the model of stability in an unstable era. Hired on May 5, 2011, he and his staff — associate head coaches Kevin Nosek and Kyle Vogt, assistant Jonathan Metzger-Jones — form one of the longest-tenured coaching groups in Division I, together for more than a decade. In a sport where rosters turn over annually and coaches change jobs every spring, UC Davis has bet on continuity, and the bet has paid: the program's best Division I records, its first Big West regular-season and tournament championships, and its first NCAA tournament berth all came under Les.
The 2017 season remains the program's north star. The Aggies won the Big West tournament, earned the school's first trip to the NCAAs, and drew Kansas in the first round in Tulsa — a David-and-Goliath date the program had waited its entire Division I life for. Chima Moneke, the Nigerian-Australian forward who became the face of the program, starred on that team before launching a professional career. The message of 2017 still echoes: UC Davis can win the big one.
The program's identity starts on defense. UC Davis has ranked among the nation's top 50 in turnovers forced in six of the last eight seasons — a relentless, disruptive style that fuels everything else. The Aggies turn defense into offense, creating the transition opportunities and early-clock looks that fit their balanced, egalitarian attack. It's a system that travels: defense doesn't slump, doesn't depend on one star, and doesn't care what league you're in. That matters now more than ever.
Last season was the farewell tour — the 19th and final Big West campaign — and it ended the era with pride. Guard TY Johnson carried the scoring load, dropping 22 in the season-opening win over Menlo, and the Aggies played their familiar brand: tough, deep, and hard to speed up. The program heads to the Mountain West with its culture intact and its roster reloaded.
The 2026-27 roster is classic UC Davis: veteran returners, international flavor, and NorCal roots. Seniors Niko Rocak — the 6-foot-9 Geneva, Switzerland forward — and Carl Daughtery Jr. provide leadership; juniors Nils Cooper, Connor Sevilla, and Brayden Fagbemi and sophomore Isaiah Chappell form the rotation's core. The newcomer class is one of the program's most intriguing: guards Marcus Wilson and Jalen Stokes, 6-foot-11 junior Jonathan Noudjihidi from Chad, 6-foot-8 Vienna native Omer Suljanovic, Helsinki's Abdullah Amzil, and French guard Ylan Esso-Essis give Les size, skill, and lineup versatility he hasn't always had. It's a roster built to compete on day one in a tougher league.
The Mountain West is a different animal. The league has been a multi-bid conference with national-title contenders, NBA talent, and some of the best home-court environments in the West. UC Davis opens its new reality with conference dates against the league's heavyweights — a January visit from New Mexico, a March trip to UNLV's Thomas & Mack Center — and every night will be a measuring stick. The Aggies were picked to be competitive in their final Big West season; in the Mountain West, they'll have to earn every bit of respect from scratch.
The home floor will be a weapon. The University Credit Union Center — the Pavilion, with its beloved Hamilton Court — has been one of the West's great home-court advantages when full, and the program twice went undefeated at home within a three-year span under Les. Mountain West road trips into Davis will be a new experience for visiting teams; Aggie fans have waited a long time for nights like these, and the building should be electric.
Les's personal milestones tell the story of the build. His 300th career win came in November 2021 against Eastern Washington; his 200th as an Aggie came in December 2024 against UC Santa Barbara. The 383 wins put him alongside names like Maryland's Buzz Williams among active coaches — and in company with Hall of Famers on the all-time lists. He has done it the hard way: no blue-chip recruits, no shortcuts, just development, defense, and patience.
For the university, the move is about ambition. UC Davis — one of the nation's top public universities, a research powerhouse with a proud Division I athletic program — has long believed its athletics should match its academics. The Mountain West invitation is the proof of concept. Basketball, the program Les built from the ground up, gets to lead the way into the new era. The Big West years produced a championship, an NCAA berth, and a culture. The Mountain West years start now, and the goal is the same as it ever was: win the league, dance in March, and make Davis believe.
