ESPN’s Mel Kiper Jr. released his latest mock draft, and the San Francisco 49ers invested in the offensive line for the first time in the first round since Mike McGlinchey.

It’s something we can expect to be popular in every mock draft cycle, but it’s 49ers offensive line coach Chris Foerster who is on record saying that he tells Kyle Shanahan to draft the guys who score touchdowns in early rounds. Will this year be any different?

Maybe. Kiper mocked a player to the Niners who does not seem like their type on paper:

Proctor’s tape is all over the place. 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. 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. 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.

Proctor is listed at 6’7″, 366 pounds. The 49ers ask their lineman to run and execute blocks on the move and in space. That does not seem like something a player of Proctor’s size would excel at. However, Bruce Feldman’s annual Freak List had Proctor listed with a 32-inch vertical jump. For reference, Trent Williams had a 34.5-inch vertical jump, which is in the 97th percentile. Proctor also had an 815-pound squat, 535-pound bench press, and a 405-pound power clean. That is a powerful human being.

Proctor wasn’t always 366. He was 400 pounds as a freshman. The concern would be Proctor regaining that weight as a pro now that he’s not being monitored as closely. That weight fluctuation could lead to inconsistencies in his play, especially his sets as a pass protector.

But we are talking about a player with the ideal frame, athleticism, and one who looks dominant when he’s engaged. Those dominant stretches don’t always last, and there is enough tape out there to be concerned, which is why he might be available when the 49ers are on the clock.

Proctor was the No. 1 offensive tackle out of his high school class and will be 21 in June. The pedigree is there. Concerns about handling speed and whether he can maintain his weight are valid, but it’s impossible to ignore his power and how he clears running lanes with ease. Plus, for a player as big as Proctor, the range is where it needs to be.

Proctor was exclusively a left tackle in college. He could play left guard next to Trent Williams, giving the Niners a talent boost they desperately need at the position.
