Nice breakdown. I assume this video was taped before Zuhn ran at the combine and put up silly numbers for a 312 lb man. But Zuhn didn’t do agility drills, which likely makes him look not as athletic on the field as he is in terms of running and jumping. The big knock seemed to be strength, followed by hands/arm technique. Both can be coached up, which is where the video concluded. Zuhn is 6’6.5” (not 6’7”) and less than 15% of NFL OG are that tall. I’m guessing where these types of OT conversions have found success is in wide zone blocking schemes. But you might be right and the team cross trains Zuhn across the entire OL, including at LT.
