Colorado has hired Xavier Adibi as defensive staff coordinator, adding the former NFL linebacker to Deion Sanders' coaching operation in Boulder. The move fills a support role on a defensive staff that has cycled through four coordinators since Sanders arrived in December 2022.
Adibi spent four seasons in the NFL with Houston and Minnesota between 2008 and 2011, recording 278 tackles across 54 games. He played linebacker at Virginia Tech under Frank Beamer, part of the program's last sustained run of top-15 defenses. The Colorado role marks his return to college football after nearly a decade away from coaching. He most recently worked in player development and community outreach roles tied to his NFL alumni network.
The hire matters because Colorado's defensive coordination remains unstable beneath the Sanders brand. Charles Kelly arrived as DC in January 2023, departed after one season, and was replaced by Robert Livingston, who lasted eight months before Sanders elevated linebackers coach Ryan Walters in December 2024. Adibi slots in as a staff coordinator—a title that typically handles film breakdown, quality control, and special-teams crossover work—rather than a position coach with direct recruiting territory. That structure suggests Sanders wants continuity in the defensive meeting room without locking in another full coordinator bet before the season.
The Buffaloes allowed 29.8 points per game in 2024, ranked 89th nationally, and gave up 168 rushing yards per contest. Sanders has said publicly that Colorado needs to "stop the run to win the Big 12," but the program has signed only three defensive linemen in the 2025 class as of early January. Adibi's film-study background could help the staff identify schematic adjustments that don't require a full roster overhaul, particularly against run-heavy Big 12 opponents like Kansas State and Iowa State.
The timing is clean. Colorado's early signing period closed in December, and the February window opens in three weeks. Adibi will have 21 days to learn the defensive playbook before the program hosts official visits for uncommitted prospects in late January. The Buffaloes are also waiting on two portal safeties—one from Auburn, one from Ole Miss—who have scheduled campus trips but not announced decisions. If Adibi can show recruits a credible plan for year-three defensive improvement, those visits carry more weight.
Watch for Colorado to announce a defensive line coach by the end of January. That hire will signal whether Sanders is prioritizing NFL pedigree or recruiting ties in Texas and California. Adibi's Virginia Tech connections don't overlap with Colorado's current recruiting footprint, which runs through Florida, Georgia, and the Dallas-Fort Worth corridor. The Buffaloes also need to finalize their special-teams coordinator after Trevor Reilly left for a role with the Los Angeles Chargers in December.
Sanders' staff now includes two former NFL players in defensive support roles—Adibi and analyst Warren Sapp—but zero assistants with Power Five coordinator experience on that side of the ball. That structure works if Colorado's offense can score 35 points per game again, but the Big 12 added Arizona, Arizona State, and Utah, all of whom finished 2024 ranked in the top 40 in scoring defense. The margin for defensive inconsistency just narrowed.
The takeaway
Adibi fills quality-control role on defense that's cycled four coordinators in two years; signals Sanders wants film help before locking another DC bet.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.

Imprint manufacturing & Komori Press · Canon high-speed secure-media operations is a craft floor — genuine Six Sigma discipline applied to ink, thread, foil, and registration, where a hundredth of an inch is the difference between a brand that reads serious and one that reads cheap. POPS4 is built by exactly those operators: independent, boots-on-the-ground engineers who carry their own book, read a client in microseconds, and put their name on every run. Beyond our own Virginia Beach floor, we work with a vetted network of craft manufacturers across the US — each meeting the highest excellence in QC standards in the industry, each a specialist in its own discipline — so apparel, hard-goods imprinting, media manufacturing, packaging, and secure printing all go to the bench built for them, coordinated from one accountable hub.
