Who Is Patrick Mahomes' Backup Quarterback?

As of the most recent offseason and training camp, the Kansas City Chiefs' primary backup to star quarterback Patrick Mahomes is Ethan Watson, a fifth-year veteran acquired via trade from the Browns. This page explains the current backup setup, recent changes, roles on the depth chart, and how the Chiefs develop quarterbacks behind Mahomes in a way designed to remain accurate across multiple seasons.

Current Depth Chart at Quarterback

Fifth Season with the Chiefs

After trading up to select Drake Maye in 2024, Kansas City shifted its QB development focus while preserving veteran presence. Ethan Watson, signed to a one-year deal in March 2025 following his release from Cleveland, is listed as the de facto No. 2 quarterback entering training camp. The stated structure places Watson as the primary starter of any preseason or Week 1 scout-team work, giving Mahomes regular reps against a live lookalike challenge.

Supporting Cast and Roster Mechanics

The Chiefs carry two quarterbacks on the active roster in most configurations, with practice squad moves and injury designations creating fluid opportunities. Watson operates within a system that emphasizes rhythm, timing, and fast-paced no-huddle concepts similar to the Mahomes-led offense. Younger quarterbacks on the practice squad receive reps with the scout team and limited preseason snaps, allowing the coaching staff to evaluate growth without pressing untested talent into regular-season action.

Backup Quarterback Responsibilities and Expectations

In modern NFL systems, the backup role extends beyond simply standing by. For the Chiefs, the backup is expected to mirror the offense, maintain film study habits, and be ready to enter the game without disrupting tempo. Watson’s experience in Cleveland and earlier with Cincinnati allows him to understand Coach Andy Reid’s terminology and check-down progressions, which reduces the cognitive load when he must step in during a game. This preparation is part of a broader organizational strategy to protect Mahomes and extend his effectiveness.

Defining the Role

• Maintain daily rep quality on the scout team to simulate upcoming opponents.
• Be prepared to call audibles and manage the game if the starter exits.
• Support practice planning by providing a consistent look week after week.

Path to the Backup Role

Ethan Watson’s route to becoming the clear backup illustrates how Kansas City balances youth and experience. After backing up Joe Flacco and then Deshaun Watson in Cleveland, he sought a situation with stronger contention. The Chiefs traded a 2025 seventh-round pick and an International Player Pathway spot to acquire him, signaling commitment to having a seasoned professional behind Mahomes. At the same time, Drake Maye remains part of the long-term plan, expected to take on increased responsibility over the next two to three years as he gains NFL experience.

Veteran Presence vs. Developmental Timeline

By choosing Watson, Kansas City prioritized immediate familiarity with the system over a rookie learning curve. This decision reflects years of offensive philosophy under Andy Reid, where quarterbacks are expected to process reads quickly and move the chains. Watson’s contract is structured for one season, keeping flexibility for future roster moves once Maye’s development reaches the next stage. The arrangement also allows the Chiefs to manage workload and protect Mahomes by ensuring quality reps in practice.

How the Backup Role Protects Mahomes and the Team

A capable backup stabilizes the locker room and maintains strategic flexibility. If Mahomes were to miss time, the Chiefs would avoid the disruption of suddenly installing an inexperienced quarterback in a high-variance offense. Instead, Watson provides a seamless transition, built on repetition and shared language. This continuity is especially important in a pass-first system that relies on complex progressions, timing routes, and rapid decision-making. By addressing the backup position proactively, the organization reduces risk without sacrificing long-term growth.

Future Outlook and Development Roadmap

Looking ahead, the Chiefs will balance short-term stability with future-building. Watson offers professionalism and system knowledge in the present, while Maye represents the next generation of talent. Roster decisions will likely hinge on Maye’s preseason performance and the competitive landscape in training camp. For fans, the key takeaway is that a prepared, experienced backup allows Mahomes to focus on execution and health, which is critical in a championship environment that demands consistency over 17 weeks.

Scout-Team and Practice Impact

During the season, the backup’s role intensifies as the scout team prepares game plans. Watson’s ability to replicate opposing coverages and defensive tendencies helps the first unit sharpen communication and timing. This dynamic benefits the entire roster, especially receivers and linemen who rely on consistent quarterback reads. A stable backup translates to sharper preparation, which in turn supports Mahomes’ in-game decision-making and reduces preventable errors.
