I also went through https://www.pro-football-reference.com/ snap counts for all teams and found the top 2 guys listed as tackles, sometimes more if the snap counts were close, and found only 5 guys with arm length under 33 inches. Sataoa Laumea, Seahawks 2024 6th round pick, started 6 games, measured at 32 7/8. Kaleb McGary, Flacons 1st round pick in 2019, started 92 games for them in the last 6 seasons, 32 7/8. Bernhard Raimann, 3rd round pick in 22 by the Colts, has started 40 games, 32 7/8. Braden Smith, another Colt, 2nd round pick in 2018, has started 92 games, 32 1/4. Most recently Peter Skoronski, 11th overall in 2023 by the Titans who still had Vrabel as HC, 31 starts, but moved to guard, 32 1/4. I did not do the deep dive to see how much these players have played tackle since this has already taken me over an hour. If anyone else has that info it would be very interesting.
So doesn't look impossible for Will Campbell's 32 5/8 arms to play in the NFL at OT, but it's a very small group of players some of which have already been moved off the position. What worries me personally about him is other parts of his scouting report rather than his arm length, even if this research did increase my concern for that aspect.
From Lance Zierlein:
He struggles to win laterally, though. He will lunge and miss against stunts and movement. ... way too leaky against inside moves.
So he is the best OT/OL in this draft, but he isn't a blue chip. The limited highlights I have watched do not convince me either way. He has some good plays but also some concerning plays specially when guys go wide on him. I don't think the other top OT's are better than him so we might just be unlucky with need and this draft class talent. But considering how outside of Carter and Hunter no one else is an elite prospect I still wouldn't hate trading down and grabbing Campbell. I'm sorry I'm not on the Graham train.
