But doesn't one essentially need to be aware of the pocket to be able to know when it's time to escape it? Lol.I think the ability to escape the pocket (which Tannehill absolutely has) and pocket awareness are two different things; the video does an excellent job of putting the former on display. Pocket awareness is more about manipulating the pass rush to put your blockers in the best position to divert (block) their assigned rusher, while maintaining eyes downfield. There hasn't been much improvement in that regard from Tannehill; however, a more free-flowing offensive scheme should expedite that phase of his development pretty quickly.
I can't lie though, you're correct in saying there's a distinct difference.
And I only saw one instance @1:00 in the video where Tannehill manipulated the rush to his advantage by using the defenders momentum against them by sliding to his left slightly buying just enough time to make the throw down the field.
Still it's difficult to evaluate his true ability to create space within the pocket because too many times the offensive line was so terrible that more often than not multiple defenders would break through the protection uninhibited causing the quarterback to abandon the pocket all together.
