The San Francisco 49ers could use the 2026 NFL Draft to secure a long-term successor to veteran left tackle Trent Williams. The question isn't whether the need exists — it's how early they're willing to address it.
If the 49ers spend a first-round pick on a future replacement, the benefit is clear. A rookie would have the rare opportunity to sit and develop behind one of the greatest offensive linemen in NFL history. That kind of experience is invaluable, especially at a premium position like left tackle.
The downside? San Francisco would be investing its top selection in a player unlikely to make an immediate impact. The 49ers must carefully weigh short-term roster needs against long-term roster needs.
With the NFL Scouting Combine underway, ESPN draft analyst Mel Kiper Jr. released his latest mock draft, projecting the 49ers to select former Alabama offensive lineman Kadyn Proctor at No. 27 overall.
The selection of Proctor might be a bit of a gamble on the 49ers' part. Kiper characterizes him as a true developmental prospect. The offensive lineman has high upside, but the analyst remains concerned with his floor.
"Proctor's tape is all over the place," Kiper wrote. "The highs are really, really good. The lows raise a lot of questions. But in the right situation, he could become a standout tackle in the NFL. And there might not be a better situation than learning behind one of the best to ever do it in San Francisco. Trent Williams will be 38 by Week 1, and he's entering the final year of his contract."
From an analytics standpoint, Proctor closed his collegiate career on a strong note. According to Pro Football Focus, he posted career-best marks in 2025 with an 86.1 overall offensive grade, an 81.1 run-blocking grade, and an 84.2 pass-blocking grade. He surrendered 21 pressures and two sacks across 611 pass-blocking snaps.
At 6-foot-7 and 366 pounds, Proctor possesses rare size, so the upside is apparent.
"So, Proctor could develop in Year 1 while kicking inside to guard and/or playing a swing tackle role before perhaps taking over for Williams in 2027," Kiper added. "He has 40 career starts -- all at left tackle -- and is reliable in pass protection. This would be an upside pick for GM John Lynch."
