I think if there are some really nifty, beautiful play designs that can break a game open, that's one thing that should be shelved until needed (e.g. Giants game, playoffs, etc).
But merely testing the receivers deep, I don't know if that's really such a big deal. It's always there on every single play (it's why you have safeties) for all 32 teams....some use it less, some use it more...but it's there.
Besides being a spoiled fan that wants to see big plays, my biggest concern is that we might not be able to flip a switch and suddenly have great success using it (hopefully I'm wrong on this). I'm all for patience and conservative football so long as these plays can be executed when needed.
At some point we have to start attacking, especially against non blitzing teams that can rush 4 and drop back more into coverage.
Regardless of great success or not, the threat should open up the LOS and short/intermediate routes a lot more.
Look at our boy here....I expect big things!!

On just about all of those deep throws there was no safety in the picture. When you actually see one he's late. It's easy to catch a long one with no safety around, but we know it doesn't work like that most of the time.
