Summary

Alex Singleton was undrafted in 2019 out of Montana State. Singleton is a dependable and mature linebacker who brings serious run‑defense ability, high tackle production, and leadership to his team. He excels in roles where he is asked to plug the interior, finish tackles, and operate with intensity and awareness.

However, his game is somewhat limited when it comes to elite coverage skills or changing direction at the very highest level. In today’s NFL, where linebackers increasingly need to cover tight ends, fullbacks, or drop deep in coverage, this is a gap in his profile. As a result, while he is a strong starter, his ceiling may not reach the “dominant two‑way linebacker” tier. He is more of a “rock solid every‑down inside linebacker with special value in run defense.”

Strengths

• Run‑defense prowess — According to Pro Football Focus, Singleton posted a run‑defense grade of 87.6 which ranked 7th out of 79 linebackers. PFF He has a knack for being around the ball, finishing runs, and contributing to gap control.

• Tackling and tackling volume — In the 2023 season, he logged very high tackle totals, showing his consistency and production in the field. Mile High Report

• Leadership and experience — His journey from undrafted to starter, combined with captaincy and his football IQ, gives him intangible value in the locker room and on the field.

• Durability in starting snaps (when healthy) — When he is fully healthy, Singleton has shown he can handle high snap counts and be the central figure in the linebacker room. Mile High Report

Weaknesses

• Coverage limitations — His coverage grade lags (48.3 / 79 LBs according to PFF). PFF He is more comfortable attacking downhill or defending the run than in more open space coverage roles.

• Athleticism / speed concerns — Some analysts note that while he is effective, his top‑end athletic traits (e.g., recovery speed vs deep plays) are less than elite. Denver Gazette

• Age & injury risk — At age 31 (as of the most recent profile) and coming off notable injuries, questions remain about how many peak years remain and his ability to maintain explosiveness. SI

• Role ceiling in modern linebacker schemes — Given his strengths and weaknesses, he may fit best as a three‑down linebacker in a traditional front rather than as an all‐purpose off‑edge/coverage linebacker in space‑heavy defenses.

Fit & Outlook

• Fit:
  Singleton fits best in defenses that emphasize physicality, run‑stopping, gap integrity, and less on matching receivers in full isolation coverage. He is especially suited to teams that rely on structure and communication more than relying solely on elite athleticism from the linebacker group.

• Outlook:

• Short‑Term: Expect Singleton to be a key contributor for the Broncos, especially if healthy, anchoring the inside linebacker spot and producing steady tackle numbers and run‑stop plays.

• Medium‑Term: If he remains healthy and the scheme protects him from being over‑exposed in mismatch coverage scenarios, he can continue being a high‑value starter. His age and previous injuries suggest monitoring will be important.
