Dre Greenlaw vs. Alex Singleton: What Denver and San Francisco reveal

dre greenlaw enters this news cycle from two directions at once: a look back at the San Francisco 49ers’ 2019 draft class and a present-day Denver Broncos linebacker room where his contract status sits beside a new deal for Alex Singleton. Placing those two snapshots side by side answers a sharper question than either can alone: is linebacker continuity being built through drafting cornerstones or extending proven stabilizers?

San Francisco’s 2019 class: Nick Bosa, Deebo Samuel, and Dre Greenlaw as pillars

The 49ers’ 2019 NFL Draft is framed as the class that defined the Kyle Shanahan 49ers, with “fingerprints” still visible in the team’s identity even years later. The top pick, Ohio State defensive end Nick Bosa, is described as the centerpiece of the 49ers’ pass rush and a player offenses planned around with double and triple teams. Even in 2025, before his season ended early, Bosa appeared in three games and helped seal late wins in two, before suffering a torn ACL in Week 3 that ended his season.

With their next selection, Shanahan drafted Deebo Samuel, a player who became a uniquely deployed offensive weapon in a “wide back” role. Samuel later moved on from San Francisco and was traded to the Washington Commanders. In 2025 with Washington, he appeared in 16 games with 72 catches for 727 yards and five touchdowns, plus 75 rushing yards and a rushing score; he might be looking for a new team in 2026 amid reports the Commanders might not bring him back.

Within that same 2019 class, Dre Greenlaw is part of the broader thesis: a later-round linebacker who fit into the spine of the roster. In that framing, the 49ers’ approach emphasizes draft picks becoming long-running reference points for scheme and identity, even as individual careers and team circumstances evolve.

Denver’s linebacker bet: Alex Singleton’s $15. 5 million extension beside Dre Greenlaw’s flexibility

Denver’s current story runs in the opposite direction: contract decisions designed to keep experience and communication intact. Linebacker Alex Singleton agreed to a two-year, $15. 5 million extension with the Broncos, a deal that includes $11 million in guarantees and marks the third contract he has signed with the team since joining on a one-year free agent deal in 2022. The Broncos are retaining a captain from a defense that ranked among the NFL’s best last season, and Singleton is described as one of the unit’s most consistent forces with a 17-game average of 162 tackles during his four seasons in Denver.

Singleton’s standing in the locker room is tied not just to production but also to resilience and responsibility. He played a game just days after being diagnosed with testicular cancer, then had surgery to remove a tumor one day after registering nine tackles and playing all 60 defensive snaps in a win against the Las Vegas Raiders. He missed only one game afterward, won Denver’s Ed Block Courage Award at season’s end, and has previously been the team’s Walter Payton Man of the Year nominee for work with Special Olympics groups.

At the schematic level, Singleton has served as the communication hub for coordinator Vance Joseph’s defense over the past three seasons, praised for making adjustments on the fly and at times pulling Denver out of the wrong call based on offensive looks. Denver also reached terms with Justin Strnad on Sunday for a three-year, $18 million contract, a deal that suggests Strnad will enter the season as a starter next to Singleton. Strnad previously started in Singleton’s place for much of 2024 and did so in place of Dre Greenlaw for half of last season.

For dre greenlaw specifically, the contract lens is different. Greenlaw remains under contract for the next two seasons, but he has no guaranteed money remaining. The Broncos could release him to save roughly $6 million in salary cap space, though Denver could also keep three veterans together, in part to guard against injuries. Greenlaw also described a coaching contrast: playing for an “old school” coach in Payton felt different from his six seasons under Kyle Shanahan in San Francisco, and learning Joseph’s defense felt like “learning Spanish when I first saw it. ”

Dre Greenlaw and Alex Singleton compared: continuity built by draft versus continuity built by extensions

Set next to each other, the 49ers’ 2019 draft rewind and the Broncos’ linebacker contracts show two different continuity engines. San Francisco’s snapshot is a roster identity argument anchored in the draft: Bosa as a foundational pass rusher, Samuel as a scheme-defining weapon, and Dre Greenlaw as part of the connective tissue described as the backbone of the Shanahan 49ers. Denver’s snapshot is a roster stability argument anchored in contract certainty: Singleton’s new guarantees, Strnad’s multi-year commitment, and the flexibility around dre greenlaw’s non-guaranteed years.

Finding (analysis): the comparison establishes that Denver is choosing controllable, contract-based continuity at linebacker, while the 49ers’ 2019 lens emphasizes identity continuity rooted in a draft class that became foundational. The next confirmed data point that will test that finding is the Broncos’ decision on whether to keep or release dre greenlaw despite the roughly $6 million cap savings available. If Denver maintains a three-veteran approach for injury protection, the comparison suggests the team values depth stability over squeezing maximum cap flexibility from Greenlaw’s deal.
