Excellent write-up. One small nitpick: on the slide that has the caption "OSU Linebackers Fill Quickly," there are arrows showing Grant and Lee filling the hole. Actually, Grant fills the hole, Lee goes outside to contain, Gordon tries to bounce back inside to avoid Lee on the outside, then Bosa tackles him.
I find the graphs to be confusing. The axis labeled "Run" is actually the pass data, and vice versa. Look at the Wisconsin. The chart would suggest that it is a below average rushing team. I get from the main chart that the line is intended to be what an average team would rush for, but that is not how the axes (not sure on plural of axis) would usually be labeled.
I think it has to be Eze. He stands to the the starting RB. Pretty big shoes to fill.
Very interesting analysis. As a fan that is not knowledgable about blocking schemes, I personally greatly prefer the videos where I can pause the video and see see what the various blockers are doing. Then I can actually see what you are talking about. It all happens so quickly in the videos that I cannot pause that it is much tougher to see how the line is working. I am not sure if you can post every video in that format, or if I am in the minority on that view, but I would suggest posting the videos so that the reader can pause and rewind the video.
