I don't know if I really buy into your theory, but one thing you said makes a lot of sense. The fact that there is a lot of inconsistency here is a bit bizarre. I mean, we're being shown the beautiful Brantley slip and the OSU TE "on-a-dime" turning in the same video. The last play with the ND run isn't shabby either. I refuse to get my hopes up again without evidence, but the mixed bag is weird. It bothers me a little bit.
Unrelated, one thing I haven't seen brought up is the identical animation seen by the DL after a thrown ball. You CAN actually see the locomotion there. It's quick but they all do take a step before moving towards the receiver's direction. 2 problems though. 1, they all do so identically, with the exact same "reaction time," if you will; it's like watching synchronized swimming, but on land. Not right. 2, the locomotion that was present there isn't enough. You can see it if yo look close, but it's still too jerky. More time needs to be taken on those pivot steps.
Bottom line, we shouldn't have to watch the video 5+ times to see the locomotion. It should be apparent in every second from the first time we hit the play button.
