I don't believe for a second that you break down film that well over the span of a few hours. Hell, Saban took three days studying the tape before he made any comment on how it went.
We saw Blake Sims. That tells you he's going to be #3 coming out of A-day.
As to the other two, there are very, very little differences in their shuttle times which is the defining athletic prowess to moving around in the pocket. You've come away with an "opinion" that one is more mobile than the other and it's just that: opinion.
There's simply not enough information available at this time to say which is better. In fact, a wasteless use of bandwidth.
The idea that you know what's been happening this spring in closed practices...how does that work? As example, going into spring camp we knew that we'd have our starting RB, 2 WR's, a TE/HB and the right tackle spot would be set. But, how the rest shuffles out? No one, no one, knows anymore today as a fan, or reporter, than they did going into camp.
That information is out there...but, seldom posted on public forums because those that share end up getting questioned.
As far as what I saw when I read your posts...regurgitation of a lot of posts on other forums. But, it goes in direct conflict with what was shared by a few parents, coaches, and former team members.
