Colorado reshuffles wide receiver coaching group as Jason Phillips departs staff

Colorado is once again adjusting the internal structure of its football coaching staff, with a change that figures to reverberate through its wide receiver operation. Yahoo Sports reported that Jason Phillips, who had been a longtime right-hand figure for Deion “Coach Prime” Sanders in the wide receivers coaching group, is no longer part of the Buffaloes program. The report points to Phillips being removed from Colorado’s official staff directory, a visible sign of how quickly Sanders’ staff turnover has continued during the offseason.

Phillips’ departure is notable largely because of the role he has played within Sanders’ staff identity. In reporting tied to the staff directory update, Yahoo Sports characterized Phillips as Sanders’ longtime assistant and wide receiver hand, suggesting a degree of continuity in a specific positional unit. When a program removes a long-standing positional coach from the public-facing staff list, it usually indicates more than paperwork. It typically reflects changes in day-to-day coaching assignments, the teaching workflow, and the way players are developed for that particular position group.

The same report also centers Brennan Marion in the evolving wide receiver plan. Yahoo Sports described Marion as working alongside a “new WR coach,” tying the change to an updated staffing arrangement for the unit. While the report’s details focus on Phillips’ removal, it frames the Marion element as part of what’s next for the wide receivers under Sanders. For Colorado, that matters because wide receiver production and route execution are often used as a measuring stick for how well an offense is functioning, especially in a system that depends on timing, precise spacing, and reliable hands.

From a roster and development standpoint, coaching staff shifts can affect multiple layers at once. Even when players remain the same, positional coaching changes can alter how receivers learn progressions, how they study film, and what the staff emphasizes in the route tree. For a program like Colorado, which has placed a premium on building an identity quickly, the wide receiver room is also a recruiting-facing unit. Coaches who recruit and evaluate prospects at the position often influence how quickly a class gels with the program’s style.

Colorado’s public staff directory updates, as described by Yahoo Sports, have tended to draw quick attention because Sanders’ program changes have been closely tracked by fans and analysts. In that context, Phillips’ removal may be less about a single decision and more about a broader staffing management approach. Sanders has relied on reshaping coaching roles as the program moves through different stages of its rebuild, and this latest personnel adjustment suggests the wide receiver unit is still being tuned to match the offense’s priorities.

What to watch next is how the wide receiver unit is configured under the revised staff. That includes who is officially listed as the primary wide receivers coach, how Marion’s responsibilities are described once Colorado makes the next staffing details clear, and whether the wide receiver room’s teaching emphasis shows up consistently in practice structure. Because the Yahoo Sports report is the core basis for this development and additional confirmation from Colorado or the relevant conference office was not identified in the available research, this item should be treated as a coaching-staff update that warrants follow-up rather than a fully resolved lineup.

Still, the direction is straightforward: Colorado appears to be recalibrating its wide receiver coaching structure by moving on from Phillips and reorganizing around Marion and a different coaching setup. In Sanders’ high-visibility program, even behind-the-scenes changes can carry immediate football meaning, particularly for a position group that can swing game plans through explosive plays and third-down conversions.
