Nuggets sign former Denver West basketball player Alpha Diallo out of EuroLeague

The Nuggets have made a habit of signing bench players with Colorado ties.

The latest homecoming they’ve arranged is for Alpha Diallo, who played a season of high school basketball at Denver West and is now signing a one-year, $1.4 million minimum contract with Denver in NBA free agency, a league source told The Denver Post on Sunday.

Diallo, 29, was named Defensive Player of the Year in the EuroLeague last season. This will be his first foray into the NBA after a five-year stint with AS Monaco. He recently committed to join Dubai Basketball on a multiyear deal, according to a report by the European media outlet BasketNews, but his contract included a clause granting his release if he left for the NBA by July 15.

The Nuggets have signed Diallo, Reggie Jackson (Palmer High School), David Roddy (Colorado State) and KJ Simpson (CU) to various deals in the last three years.

Born in New York, Diallo helped lead Denver West to the Colorado Class 4A Sweet 16 as a sophomore. He transferred to Lincoln High before his junior season, but he was ruled ineligible to compete for the entire school year due to what CHSAA deemed an implicit recruiting violation; Lincoln’s coach at the time had just coached Diallo in a summer tournament.

The eligibility fight with CHSAA eventually led Diallo to leave the state. He returned to the East Coast and played four years of college basketball at Providence, where he earned Second Team All-Big East honors twice.

Signing Diallo is the latest example of Denver’s attempt to prioritize defense and athleticism around Nikola Jokic. Last month, the Nuggets drafted Trevon Brazile and Bryce Hopkins in the second round, betting on defensive upside in both cases. They’ve also replaced backup center Jonas Valanciunas with the younger, bouncier Marvin Bagley III on a veteran minimum contract.

Denver tentatively has 12 players under contract on its 15-man roster for the 2026-27 season now: Nikola Jokic, Jamal Murray, Aaron Gordon, Cam Johnson, Christian Braun, Zeke Nnaji, Julian Strawther, DaRon Holmes II, Tyus Jones, Bagley, Brazile and Diallo. Restricted free agency negotiations have not yet been resolved with Peyton Watson and Spencer Jones.

Diallo will count for $2.45 million toward the luxury tax despite his $1.4 million salary, the minimum for NBA rookies. The accounting quirk exists so that owners aren’t incentivized to overlook more experienced free agents for tax purposes; the tax ramifications are equal for all minimum signings, regardless of NBA service time.
