Summary

Alex Singleton entered the NFL as an undrafted free agent in 2015 out of Montana State University. A former college quarterback turned linebacker, Singleton took an unconventional path to the NFL, developing his game through special teams, practice squads, and time in the CFL before earning a full-time opportunity. At Montana State, he was a highly productive defender, recording 230+ total tackles, earning All-Big Sky honors, and serving as a team leader. In the NFL, Singleton emerged as one of the league’s most productive tackling linebackers, particularly during his tenure with the Denver Broncos. Through the 2024 season, he has totaled 700+ career tackles, with multiple seasons exceeding 150 tackles, and added tackles for loss, sacks, forced fumbles, and pass breakups. He earned Second-Team All-Pro honors (2023) and has been a team captain, widely respected for his work ethic, toughness, resilience, and leadership. Singleton’s shared story of how a NFL Drug Test flagged him for early testicular cancer was an inspirational tale of checking yourself early, and his ability to reintegrate back into the squad so quickly after treatment is a testament to his dedication to the game.

Strengths

• Tackle Machine: Consistently around the football and racks up stops. Handles heavy snap counts without drop-off and responds well after negative plays.

• Doctorate Diagnostics: Diagnoses run fits quickly and attacks downhill decisively. Strong understanding of leverage and pursuit angles.

• Energy Bringer: Vocal communicator who sets defensive tone and energy. Relentless pursuit and plays every snap at full speed.

• Competitive Toughness: Brings toughness and edge to the second level. Effective as a blitzer when attacking downhill gaps.

Weaknesses

• Limited Athlete: Can be stressed by dynamic backs and tight ends in space. Better in zone when he can key in on his cerebral strengths than isolated man assignments.

• Change of Direction: Lateral agility is functional but not elite.

• Picked On in Pass Game: Can be targeted in pass-heavy game plans, especially against foes featuring heavy spread/hurry up concepts.

• Block Shedding: Relies on effort more than hand technique against linemen. More tackle-volume than splash-play driven.

Outlook

Singleton is an ideal fit for physical, effort-driven defensive systems that value run defense, tackling consistency, and leadership at linebacker. In Denver, he profiles best as an early-down MIKE linebacker, where his instincts and downhill aggressiveness can set the tone against the run and keep defenses on schedule. Pairing Singleton with a stronger coverage linebacker allows him to maximize impact while limiting exposure in space. Looking ahead, Singleton projects as a high-floor starter or core rotational linebacker whose value is rooted in reliability, toughness, and leadership. While coverage limitations cap elite three-down upside, his instincts, durability, and motor make him a trusted defensive presence. For a team emphasizing culture, effort, and accountability, Singleton remains a winning-value veteran capable of anchoring the run defense and elevating overall defensive intensity.
