They chopped the hell out of this video. You're missing a lot of the presentation elements.
I'm shocked, OS is being a LOT harder on the video than you guys are. There are issues here that the CD guys pounded on. As I pointed out over there, I was told there that most of them wouldn't' be touched too much until Beta, and this is a two week old video (Beta just started)... so as a quick couple of things I know will likely change (unless there's a serious balance issue they can't address)...
* Pockets will be tighter and set up quicker
* Defensive linemen will fire off the line faster
* Handfighting/jostling between DBs will be more commmon
* QB drop after setting should become more difficult (in fact, I'm sure of this, I've seen a more recent video)
* DEs will get off blocks going up field more effectively.
Now, if in 2-3 weeks we're getting videos exactly like this, I'll start worrying.
