The play @ 40 secs I wonder why Purdy didn't pull the trigger there. Juice was wide open with Aiyuk drawing 3 defenders, I've seen him make these throws before too. Fortunately he scrambled and still found juice later.
I think there are a couple of reasons -
1) The play looks like it's meant to put Deebo and Aiyuk in dangerous positions, with Juice stretching the defence with surprise deep threat. The defence actually covered all three aspects really well, forcing Purdy to abandon the concept.
2) It looks like Juice is supposed to go long, but (as mentioned in the breakdown) the safety has read that threat well. Brock can't just throw to where Juice is now, he has to anticipate that Juice will continue his route and not just sit. If it was Kittle he'd probably just sit, because Kittle does ridiculous stuff like that (ha ha!), but Juice would have continued right into the defender's zone.
Juice broke out of his assignment once he saw the play had broken down, and made a great scramble drill play.
