This whole offense is designed to attack the whole field and threaten that at all times.
1 - We don't attack the wings with bubble screens any longer as they don't get called,
2 - the running game cant function between the tackles.
3 - We rarely run slant patterns or seam patterns to the middle of the field. (our defense still has trouble defending a slant, yet we run very few. Mind boggling)
So an offense that is designed to be able to attack the whole field spread the defense out to make them defend the whole field and get playmakers in space, just simply doesn't do any of those things and becomes very easy to defend.
